Problems solved by technology

[0003] At present, when the high-voltage DC circuit breaker is in use, there are still great potential safety hazards. Because arcs are easily generated in the high-voltage DC circuit, the circuit breaker is easily damaged after use, and the DC circuit cannot be used for a short time after being damaged. To continue working, a new circuit breaker needs to be replaced. The replacement of the circuit breaker is not only time-consuming and laborious, but also delays the power-on time of the DC circuit

Abstract

The invention relates to the technical field of circuit breakers, in particular to a high-voltage direct-current circuit breaker which comprises a shell, a reset mechanism is arranged on the shell, a power-off mechanism connected with the reset mechanism is arranged in the shell, a segmentation mechanism is arranged in the power-off mechanism, and a traction mechanism is connected to the power-off mechanism. The traction mechanism is arranged in the shell, and a relay is connected to the upper portion of the reset mechanism; according to the high-voltage direct-current circuit breaker, the reset mechanism which is disconnected can be reset conveniently through the arranged reset mechanism, the reset mechanism can drive the power-off mechanism to reset, and thus the high-voltage direct-current circuit can operate normally after the power supply is switched on, and the reset mechanism is controlled through the arranged relay; the reset mechanism drives the power-off mechanism quickly to disconnect the power on process of the high-voltage direct-current circuit; and rapid power-off time of power-off mechanism is shortened through arranged traction mechanism, so that closed loop is formed by high-voltage direct-current circuit conveniently.

Description

technical field [0001] The invention relates to the technical field of circuit breakers, in particular to a high-voltage direct current circuit breaker. Background technique [0002] The DC circuit breaker combines power electronic devices and is a circuit breaker used to break the DC circuit. The moment when the DC breaks is realized is the current zero crossing point. DC circuit breakers can generally be divided into mechanical DC circuit breakers, solid state DC circuit breakers and hybrid DC circuit breakers. When the contacts of the circuit breaker are broken, an arc will be generated immediately between the moving and static contacts, which not only hinders the timely breaking of the circuit, but also causes the contacts to burn out. [0003] At present, when the high-voltage DC circuit breaker is in use, there are still great potential safety hazards. Because arcs are easily generated in the high-voltage DC circuit, the circuit breaker is easily damaged after use, an...
