High-voltage outdoor AC vacuum circuit breaker is mainly used in three-phase AC power supply systems with rated voltage and AC frequency. This equipment can provide its own operating power supply, and a two-phase or three-phase power supply is installed inside. Transformer is used to detect online operating current and determine the actual operation of the switch. In order to realize over-current protection, over-current timely protection and quick-break protection functions, an independent zero-sequence or three-phase synthetic zero-sequence current transformer is installed to detect the three-phase zero-sequence component to achieve small current grounding (i.e. single-phase grounding) protection. Function, cooperate with the terminal. Through R, etc., human-machine dialogue and remote control setting functions are realized. It is used at the line interface to effectively isolate the fault area within the user boundary to protect the normal operation of non-faulty lines and function as a demarcation switch (i.e. electronic power gatekeeper). dog) function, it is the preferred device for users.
Conditions of use:
Ambient air temperature: ℃~+℃ Daily temperature difference: daily temperature change is not greater than ℃ According to the properties of gas substances, when the ambient temperature is ℃, if the internal air pressure of the box is., this It is still in gaseous state, ensuring the normal operation of the product. (When the ambient temperature is ℃ and the gauge pressure is ., the liquefaction point is ℃ and zero gauge pressure, and the liquefaction point will not exceed ℃).
, the wind speed is not greater than /
, and there is no place with flammable, explosive hazards, strong chemical corrosives (such as various acids, alkalis or thick smoke, etc.) and severe vibration.
, Altitude: ≯
, Coverage thickness:
, Air pollution level: level
, Earthquake intensity: ≯ level
, Grid neutral point grounding method: Neutral The point is not grounded, the neutral point is grounded through the arc suppression coil, and the neutral point is grounded through low resistance.
Product features:
Ideal equipment for urban and rural power grid transformation:
The vacuum circuit breaker can be matched with an intelligent controller to form an automatic recloser and realize the functions of a recloser, as well as remote control, telemetry, Remote signaling, remote adjustment
. Flexible and convenient operation:
This product is electric energy storage, electric switching, and also has manual energy storage, manual switching, and can be operated remotely at short or long distances< br/> .Excellent breaking performance:
Can break short-circuit current up to times
.Low operating power and high reliability:
Newly designed small electric spring mechanism, the operating power of the number of parts is ( about) are reduced to the lowest level
. Maintenance-free features:
The main circuit of the circuit breaker, secondary components, and operating mechanism are sealed in gas & (zero gauge pressure)&, and are not affected by the external environment Impact
. Reliable sealing performance:
Adopt mature sealing structure technology, reliable sealing performance
.Unique way of incoming and outgoing wires:
Use silicone rubber sleeve to make the connection between terminals The insulation distance is sufficient and the external insulation characteristics are excellent
. Safe to use:
An explosion-proof device is installed on the top of the box. Even if an unexpected internal failure occurs, no high-temperature gas or splash will leak out.
