< - . . , Switch structural characteristics
! .
. The high-voltage circuit breaker adopts a three-phase pillar structure, with stable and reliable breaking performance. It has the characteristics of no danger of combustion and explosion, maintenance-free, small size, light weight and long service life.
! .
. The high-voltage circuit breaker adopts a fully enclosed structure with good sealing performance, which helps to improve moisture-proof and anti-condensation performance, and is especially suitable for use in cold or humid areas.
! .
. The three-phase pillars of high-voltage circuit breakers and current transformers are made of imported outdoor epoxy resin solid insulation, or indoor epoxy resin-wrapped silicone rubber solid insulation has high and low temperature resistance, UV, aging resistance and other characteristics.
! .
. The operating mechanism of the high-voltage circuit breaker adopts a miniaturized spring operating mechanism, the energy storage motor has small power, and the opening and closing energy consumption is low. The mechanism transmission adopts true dynamic transmission mode and the number of parts is small. , high reliability. The operating mechanism is placed in a sealed mechanism box, which solves the problem of corrosion of the operating mechanism and improves the reliability of the mechanism.

. ,
.
. The opening and closing operations of the high-voltage circuit breaker can be manual or electric operation and remote remote control operation. It can be used with intelligent controllers to realize power distribution automation, and can also be used with recloser controllers to form automatic reclosers and sectionalizers.
! .
. High-voltage circuit breakers can be equipped with two-phase or three-phase current transformers for over-current or short-circuit protection. They can also provide current acquisition signals to intelligent controllers and can be added according to user requirements. Install current transformer for measurement.
! .
. . The high-voltage circuit breaker can be equipped with an external three-phase linkage isolating switch. When the isolating switch is in the open state, there is an obvious fracture, and it has an anti-mistake interlock with the circuit breaker body. device, the circuit breaker can only be operated when the isolating knife is fully closed or fully open. The arrester pillar insulator can be connected for easy maintenance.
