Problems solved by technology

[0005] However, during the actual installation process, the installer often encounters the problem of reverse connection of the incoming and outgoing wires of the circuit breaker, that is, the external wires are connected from the outgoing wires, while the internal wires are connected from the outgoing wires. The incoming line is connected; once the circuit breaker is connected in reverse, when the leakage current passes through the circuit board to open the leakage electromagnetic system, the leakage electromagnetic system will not be disconnected with the tripping of the circuit breaker, but will continue to work Until it burns, which greatly shortens the working life of the release
And if you want to solve it through circuit board control, you need to add a single-chip microcomputer for control, so that the price of the electromagnetic system is about 50 times higher than that of the existing structure, which cannot meet the cost requirements of the manufacturer.
[0006]In addition, in the current circuit breaker structure, since both the actuator and the contact system are directly installed on the When the actuator and contact system are installed, it is easy to cause the parts on the other side to fall, which increases the difficulty of installing the circuit breaker
And since the above-mentioned functional components all need to be installed with the circuit breaker housing as the carrier, the actual installation process of each component in the circuit breaker needs to be carried out sequentially in multiple processes; thus resulting in the extension of the overall installation process of the circuit breaker and the production efficiency. Decline
[0007] Therefore, the existing double-pole circuit breakers have problems such as leakage problems that cannot be displayed, circuit boards that cannot be powered off normally, and installation that is difficult

Abstract

A bipolar circuit breaker with a display function disclosed by the present invention comprises a circuit breaker shell, a first execution mechanism and a second execution mechanism are arranged at thetwo sides of the circuit breaker shell respectively, and the first execution mechanism and the second execution mechanism are both equipped with the moving contacts. One side of the first executing mechanism and one side of the second executing mechanism are connected with an electric leakage electromagnetic system and a short-circuit electromagnetic system respectively, and the other side of thefirst execution mechanism and the other side of the second execution mechanism are both connected with handles. The first execution mechanism is connected with the electric leakage electromagnetic system through an electric leakage display mechanism, and the electric leakage display mechanism comprises an indication accessory. A first linkage part is arranged between the indication accessory andthe first execution mechanism, an indication piece is connected to the inner side of each handle, and one side of the indication piece is connected with the indication accessory through a second linkage part. According to the present invention, the electric leakage display effect can be achieved when the circuit breaker is switched off due to electric leakage, and the bipolar circuit breaker has the advantages that the circuit board is good in power-off stability, and the circuit breaker is convenient to install.

Description

technical field [0001] The invention relates to a double-pole circuit breaker, in particular to a double-pole circuit breaker with a display function. Background technique [0002] Double-pole circuit breakers are generally composed of two sets of contact systems, arc extinguishing systems, actuators and electromagnetic drive mechanisms. Connect external lines; two sets of electromagnetic drive mechanisms are usually leakage electromagnetic systems for leakage protection and short-circuit electromagnetic systems for short-circuit protection. When there is leakage or short circuit in the external line, the release device corresponding to the electromagnetic system detects it and then pushes it outward, and then the actuator is pushed by the push to make the dynamic and static contacts separate from each other through linkage, and at the same time drive the handle to rotate to Open state; when the external circuit has an overcurrent problem, the thermal tripping mechanism is ...
