Problems solved by technology

[0002] At present, there are many specifications for the control power supply voltage of the remote tripping shunt release of the circuit breaker, AC50Hz 230V, 400V; DC220V, 110V, 24V, etc., and the user customizes according to different voltage specifications. To modify the circuit breaker, it is necessary to disassemble the circuit breaker to change the components in the electrical circuit, which is labor-intensive and time-consuming, which brings a lot of trouble to the user and is very inconvenient

Embodiment Construction

[0008] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples, and detailed descriptions are as follows with accompanying drawings:

[0009] Such as figure 1 , 2 As shown, the shunt release coil J in the remote trip shunt release control circuit of the circuit breaker, the normally closed contact of the micro switch K connected in series with the coil inside the shunt release and the normally open contact of the intermediate relay KA After the points are connected in series, connect the shunt release power supply voltage input terminals A1 and A2. The two ends of the coil of the intermediate relay KA are connected to the user control power supply voltage US.

[0010] For example: the current capacity of the contact of the intermediate relay KA is 1A, the coil of the shunt release J is a 400V coil, and the normally closed contact of the micro switch K connected in series with the coil inside the shun...

Abstract

The invention relates to a circuit breaker with optional control supply voltage, which is characterized by comprising a control circuit of a breaker remotely-tripping shunt tripping device, wherein the voltage input end of the control circuit is connected with the supply voltage of the shunt tripping device; the normally-open contact of an intermediate relay is connected with the control circuit of the breaker remotely-tripping shunt tripping device in series; and the two ends of an intermediate relay coil are connected with user control supply voltage. In the circuit breaker with the optional control supply voltage, the normally-open contact of the intermediate relay is connected with the control circuit of the breaker remotely-tripping shunt tripping device in series and the two ends of the intermediate relay coil are connected with the user control supply voltage, so a user can remotely control the circuit breaker through the control supply voltage of different specifications as long as the user changes the intermediate relay which corresponds to the control supply voltage, the cost and the working time of the user can be saved, the cost is reduced, efficiency is improved and great convenience is brought.

Description

Technical field [0001] The invention belongs to a plastic case type circuit breaker, and in particular relates to a circuit breaker with optional control power supply voltage capable of remotely tripping a shunt control circuit. Background technique [0002] At present, there are many specifications for the control power supply voltage of the remote trip shunt release of the circuit breaker, AC50Hz 230V, 400V; DC220V, 110V, 24V, etc., and users can customize them according to different voltage specifications. If the control power supply voltage changes, you need to correct To transform the circuit breaker, it is necessary to disassemble the circuit breaker to change the components in the electrical circuit, which is time-consuming and time-consuming, causing a lot of trouble and inconvenience to the user. Summary of the invention [0003] In order to solve the technical problems existing in the known technology, the present invention provides an optional control power supply volta...
