Core Function Of Vacuum Circuit Breaker

High Voltage Vacuum Circuit Breaker:

1. Outdoor high-voltage vacuum switch (hereinafter referred to as "circuit breaker") is used in three-phase power system with AC voltage of 50 Hz and rated current of 12 kV, and is used for load current, load current and short-circuit fault current;

2. The circuit breaker can be configured to identify current characteristics and realize multiple automatic closing or permanent failure protection;

3. The standby PT is used as a switch power supply to make it an intelligent circuit breaker with working voltage and current data signals and can be operated;

4. The three-stage complex maintenance provided by the electronic PT includes overcurrent delay, impulse voltage delay, and short-circuit fault fast disconnection.

Functional characteristics of vacuum switch:

1. Spring operating mechanism can be used, with main components such as load current, load current and short-circuit current;

2. The coordinated use of circuit breakers and circuit breakers can form a "combined circuit breaker" with a clear disconnection surface (hereinafter referred to as "combined circuit breaker");

3. Silicone rubber shields can be used on the blades. This shield is resistant to rain, sand, and dirt erosion, and can effectively prevent the freezing of the blades and oxidation of the air;

4. The circuit breaker can be converted into a high voltage and installed on either side of the incoming and outgoing lines according to the user's requirements;

5. The circuit breaker can be skillfully increased with an impact voltage regulator to avoid impact and current interruption;

6. The circuit breaker can be converted into 2 to 3 precision detection or measurement calibration instruments;

7. A closing type intelligent switch composed of a matching controller;

8. Standard and combined controllers cooperate with each other, suitable for easily available occasions, PT type and combined controllers can cooperate with each other and are suitable for occasions where switching is not required, while intelligent circuit breakers are suitable for radial power supply and dual-circuit power supply, power supply, power supply, power supply and power supply, etc.

9. The disconnecting device has 1~3 closing functions and can adjust the main parameters;

10. The intelligent circuit breaker can realize the three-stage comprehensive maintenance function, namely: voltage control, overcurrent protection, short circuit fast disconnection, and can continuously adjust the main indicators;

11. The grounding function of the intelligent circuit breaker is low voltage protection, and can continuously adjust the main indicators;

12. The intelligent circuit breaker can realize remote control, and can also be controlled by remote control lever;

13. It can be equipped with a transformer, which can provide 380 V, 110 V and 100 V as needed. V operating voltage, the transformer can obtain power from the high voltage side of the line;

14. This switch (small hydropower type) can be used to monitor the voltage of the line operation. When overloaded or working at low voltage, the switch is automatically cut off. It is generally used to connect small hydropower systems with the power grid to realize the monitoring of the power grid and automatic protection of common faults;

15. The circuit breaker (measurement and verification) can provide 0.2 accuracy working voltage and current data signals, which is an ideal choice for power switching for rural power substations, external station scattered power supply and simple metering verification;

16. The electronic device PT can be used to supply power from CT to the battery, which can perform multiple energy storage and actual operation of the reclosing switch, and can provide the standard voltage for the operation of external devices;

17. It has three functions: reclosing impulse voltage manipulation, overcurrent protection, short-circuit fast disconnection and other functions. The basic parameters of maintenance can be continuously adjusted by the user;

18. It can operate the cable TV remotely and remotely under the pole by remote control.
