Chengdu supplies 35KV outdoor isolation vacuum switch remote control operation

Chengdu supplies 35KV outdoor isolation vacuum switch remote control operationIt is a vacuum circuit breaker that can be filled with SF6 gas and has functional differences. ZW20 can be referred to as ZW20 watchdog. When it comes to watchdog, it is obvious that it is a set of intelligent switch system composed of ZW20 switch and intelligent controller. Just like a loyal dog companion guarding our switch (circuit breaker), we immediately respond to any data or updates. ZW20 column switch boundary vacuum circuit breaker primary and secondary fusion complete set of column circuit breakers, F is the abbreviation for boundary switch. The switch body can be equipped with an isolation knife switch and can be used with GW9 or HGW9.

Our company mainly produces power equipment such as high-voltage circuit breakers, high-voltage isolating switches, high-voltage metering boxes, high-voltage ring main units, high-voltage load switches, high-voltage fuses, lightning arresters, etc. If you need product information or technical support, please contact us!!

ZW32-40.5M permanent magnet vacuum circuit breaker is a comprehensive protection outdoor intelligent switch independently developed by our company. It mainly consists of three parts: the vacuum circuit breaker body, the controller, and the external voltage transformer. The three are electrically connected through aviation sockets and outdoor sealed cables, with fault detection function, protection control function, and communication function. It can reliably judge and detect the milliampere level zero sequence current and phase to phase short-circuit fault current on the input and output sides of the switch, and automatically cut off single-phase grounding faults and phase to phase short-circuit faults.

The circuit breaker adopts a permanent magnet operating mechanism, and its mechanical life is 30000 times. Within 30000 times, there is no need for maintenance or adjustment, achieving high reliability and long life.

ZW32-12/630A vacuum circuit breaker manufacturer classification configuration: This vacuum circuit breaker is divided into two types according to the operating mechanism: spring operated mechanism and permanent magnet operated mechanism. The models are ZW32-12T and ZW32-12M, and the permanent magnet operating mechanism is divided into two types: bistable and monostable. ZW32 vacuum circuit breaker can be equipped with CT overcurrent protection, isolation switch, outdoor PT, intelligent controller (watchdog), metering box device, etc. according to user requirements, to meet various occasions.

Structural features:

1. The shell is made of stainless steel material or ordinary copper plate treated with Dacromet anti rust technology and then sprayed with UV resistant varnish. The product has excellent environmental resistance such as corrosion resistance and salt spray resistance.

2. The insulation part adopts epoxy resin and silicone rubber load insulation materials, with high insulation level, strong anti pollution ability, ozone resistance, UV resistance, hydrophobicity, and high and low temperature resistance. There is no transformer oil or sulfur hexafluoride gas inside the box, which meets the requirements of oil-free transformation and environmental protection.

3. The operating mechanism can be divided into manual and electric types, and can be equipped with a remote control device and a surge avoidance device when needed. The external power supply has a power of no more than 70W and is easy to equip with a backup power supply. The designed buffering device has low performance, minimal rebound, and low noise.

4. The arc extinguishing chamber adopts special stainless steel brazing technology, which does not require electroplating, has high welding quality, and low air leakage rate. The ceramic metallization formula and ceramic metallization process are used in the production process to ensure the airtightness of the product, with a tensile strength greater than 130Mpa

5. The current transformer is made of magnetic conductive materials, epoxy resin, and silicone rubber load insulation, and has the advantages of large capacity, high dynamic and thermal stability multiple, high precision level, maintenance free, and high reliability.
