W32 type vacuum switch:

1. The ZW32-12 series outdoor high-voltage vacuum switch (hereinafter referred to as the "circuit breaker") is used in a three-phase power system with an AC voltage of 50 Hz and a rated current of 12 kV, for the purpose of controlling load current and interrupting short-circuit fault current;

2. Circuit breakers can be configured to recognize current characteristics and achieve multiple automatic closing or permanent-failure protection functions;

3. Using the backup PT as a switch power supply, making it an intelligent circuit breaker with working voltage and current data signals and operable;

4. Three stages of complex maintenance provided by electronic PT, including overcurrent delay, impulse voltage delay, and rapid disconnection of short circuit faults.

ZW32 type capacitor

The functional characteristics of ZW32 vacuum switch:

1. It can adopt a pop-up yellow operating mechanism with main components such as load current interruption, load current, and short-circuit current, and is a standard model of ZW32-12 series;

2. The collaborative use between circuit breakers can form a "combination circuit breaker" (hereinafter referred to as "combination circuit breaker") with a clear breaking surface;

3. The silicone rubber cover that can be selected for use on the blade has the characteristics of resistance to rainwater, wind and sand, and pollution erosion, which can effectively prevent the blade from freezing and air oxidation;

4. Circuit breakers can be modified to high voltage and installed on either side of the incoming or outgoing lines according to user requirements;

5. Circuit breakers can skillfully add surge voltage regulators to avoid surges and disconnections;

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

7. A closing type intelligent switch composed of matching controllers;

8. Standard and combination controllers cooperate with each other, suitable for easily accessible situations. PT and combination controllers can cooperate with each other, suitable for situations that do not require switching. Intelligent circuit breakers are suitable for radial power supply and dual circuit power supply.

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

10. Intelligent circuit breakers can achieve a three-stage comprehensive maintenance function, namely: voltage control, overcurrent protection, short circuit rapid disconnection, and can continuously adjust various main indicators;

11. The grounding function of intelligent circuit breakers is low voltage protection and can continuously adjust various main indicators;

12. Intelligent circuit breakers can be remotely controlled or controlled through a remote control lever;

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

14. This type of switch (small hydropower type) can be used to monitor the voltage of the line operation, automatically cutting off the switch in case of overload or low operation. It is generally used for connecting small hydropower systems to the power grid, achieving monitoring of the power grid and automatic protection against common faults;

15. This circuit breaker (measurement and calibration) can provide 0.2 precision working voltage and current data signals, making it an ideal choice for power supply switching in rural power grid substations, external stations with scattered power supply, and simple measurement and calibration;

16. Electronic device PT can be used to supply power from CT to the battery, which can perform multiple energy storage and actual operation of switching on and off, and can provide standard voltage for external device operation;

17. It has three functions: overlapping impulse voltage control, overcurrent protection, and short circuit quick cut-off. The basic maintenance parameters can be continuously adjusted by the user;

18. It can be remotely controlled for cble TV operation, either from a remote location or from under the pole.
