30kV Pulsed Field Vacuum Interrupter Tester, Non-Disassembly VCB Vacuum Degree Analyzer

Product Description

it is the latest generation of products of my company, it is the upgrade product in the base of vacuum meter on the foundation of notion from the field user. The vacuum tester has some features-higher measurement accuracy, better stability, more capacity.
For vacuum circuit breaker, the method of determining whether or not deterioration of the vacuum tube is inspection with the method of frequency withstand voltage, but this method only distinguish the vacuum interrupter arc chamber of the serious deterioration. When the vacuum of vacuum interrupter arc chamber degrade to 10-2-10-1 Pa, although the breakdown voltage is not reduced, but the interrupter arc chamber has failed. In the vacuum tester for vacuum switch, the new field coils were used, and with the magnetron discharge method the vacuum of the vacuum interrupter arc can be measured without disassembling the interrupter arc chamber. At the same time, the vacuum tester also used computer for synchronous control, data acquisition and processing, and the sensitivity of the vacuum tester in the field test of the vacuum interrupter arc chamber is 10-5Pa. The most prominent feature of this instrument is to use the new excitation coils and data processing methods to achieve the non-demolition measurement of vacuum. The instrument is practical, easy to use, easy to operate, high precision measurement without disassembly, widely used in electric power, steel, petrochemical, textile, coal, railways, and other trades using the vacuum switch.

Question 1: What is the test principle of this 30kV vacuum interrupter tester?
Customer: We want to learn about the working principle of this pulsed field vacuum interrupter tester. How does it detect vacuity without disassembling VCB?
Manufacturer: It adopts pulsed field non-destructive testing principle. The instrument applies pulse voltage to the vacuum interrupter, collects the discharge signal inside the tube, calculates residual gas pressure according to signal characteristics, and realizes vacuum degree measurement without dismantling the vacuum circuit breaker.
Question 2: What type of vacuum circuit breakers can this tester apply to?
Customer: Our substation has multiple types of VCB. Which vacuum interrupters is this 30kV vacuum degree analyzer suitable for?
Manufacturer: It is applicable to 10kV ~ 30kV indoor vacuum circuit breakers, including fixed type and handcart type VCB. It can test vacuum interrupters of most mainstream brands and complete the vacuity inspection directly on switchgear without removing the interrupter.
Question 3: What parameters can this vacuum interrupter tester measure?
Customer: What data can we get after testing the vacuum tube with this pulsed field vacuum degree tester?
Manufacturer: The instrument mainly measures the vacuum degree value of vacuum interrupter, judges whether the vacuity meets operation standard. It can record test data, store test results, and automatically judge qualified or unqualified status for field maintenance personnel.
Question 4: What preparations are needed before on-site vacuum degree test?
Customer: What work should our technicians complete before carrying out non-disassembly vacuum test on VCB?
Manufacturer: Cut off power of the tested vacuum circuit breaker and confirm isolation from power grid. Clean the surface of interrupter shell to remove dust and moisture. Connect test cable correctly according to operation manual. Keep test area dry and away from strong electromagnetic interference.
Question 5: What are the common fault tips during vacuum interrupter testing?
Customer: What should we do if abnormal signal appears during field vacuum degree measurement?
Manufacturer: Check the test cable connection status and clean test contact points first. Confirm the tested VCB is fully powered off. Check whether surrounding environment has strong electromagnetic interference. Restart the tester and test again. If abnormality still exists, stop test and contact technical support. Do not open the instrument casing privately.
Question 6: Shipping Method
Customer: If we place an order, how do you typically ship the goods? Will there be any issues with transporting bulky items such as reactors?
Manufacturer: We default to using dedicated logistics lines or brand-specific express shipping services; small-sized main units and accessories may also be shipped via standard courier services. Large items, such as reactors and excitation transformers, are packed using wooden crates or wooden frames for reinforcement to prevent bumps and moisture exposure during transit; a packing list is included with each package to facilitate item-by-item counting for you. Logistics costs are typically determined by both parties in accordance with the contract terms; after shipment, we will send you both the tracking number and the carrier's contact phone number for easy tracking.If your project site is remote or if delivery to the site is required with a specified logistics company, please inform us in advance when placing your order; we can then coordinate and arrange accordingly.
Question 7: Delivery Lead Time
Customer: Our project is under tight deadlines; how long will it take for the order to be shipped after we place it? Can we request expedited shipping?
Manufacturer: Standard specifications – stock available; typically delivered upon receipt of the order. Orders can be shipped within [X] working days; for non-standard products requiring customized voltage levels, capacities, or reactor combination configurations, the production cycle typically ranges from [X] to [Y] days.The delivery time will be approximately 7-15 working days; the specific timeline shall be subject to the sales confirmation provided upon order placement. If your project has a tight schedule, please inform us of the latest expected delivery date before placing your order; we will first verify the production schedule and inventory status, and where possible, will coordinate expedited production and prioritize shipment. However, it is recommended to allocate sufficient transit time for logistics to avoid delaying on-site testing.

After the warranty period expires, we still offer repair services, with spare parts supplied at cost price for the long term, and software updates provided free of charge for life. Upon delivery of the equipment, we also offer free operational training (video operation guides)to ensure that your testing personnel can operate the equipment independently and proficiently; should you have any further questions, please feel free to contact our dedicated after-sales hotline directly.
Question 9: Shipping methods for each region (Sea freight)
Customer: Our projects are distributed across several states, and our procurement volumes are substantial; are the shipping methods consistent across all states? How is the delivery time calculated?
Manufacturer: The specifications are identical; however, it should be specifically noted that this equipment set is large in size and heavy in weight—components such as the reactor and excitation transformer are all classified as heavy components. Therefore, regardless of which state or region the shipment is destined for, we will uniformly utilize sea freight transportation. The packaging employs export-grade wooden crates with reinforced structures, along with moisture-proof and rust-proof treatments; the design of these wooden crates is optimized for long-distance sea transport and multiple lifting and transshipment operations. Upon arrival at the destination, simply unpack the goods and conduct an inspection before putting them into use. Regarding delivery time, the sea freight transit period depends on the port of destination: near-sea routes are generally faster, whereas ocean routes may take longer; the exact number of days will be confirmed based on the shipping schedule specified in the bill of lading. We have a dedicated freight forwarding agency to handle booking of shipping space, customs declaration, insurance, and other related procedures; once the vessel departs, we will send you documents such as the bill of lading and the packing list, enabling you to arrange for the receipt of goods at the port of destination and their inland transshipment in advance
