Description
Technical Field
The invention relates to a bipolar circuit breaker, in particular to a bipolar circuit breaker with a display function.
Background
The bipolar circuit breaker generally comprises two groups of contact systems, an arc extinguishing system, actuating mechanisms and electromagnetic driving mechanisms, wherein the two groups of systems are arranged on the left side and the right side of a shell of the circuit breaker in a mirror image manner, and one group of actuating mechanisms is connected with an external circuit through a thermal tripping mechanism; the two sets of electromagnetic drive mechanisms are typically a leakage electromagnetic system for leakage protection and a short-circuit electromagnetic system for short-circuit protection. When the external circuit has the problem of electric leakage or short circuit, the tripper corresponding to the electromagnetic system detects the external circuit and pushes the external circuit outwards, and then the actuator pushes the external circuit to separate the moving contact and the static contact from each other through linkage, and simultaneously drives the handle to rotate to an open state; when the external circuit has overcurrent, the thermal tripping mechanism is heated and bent to realize disconnection.
Although the above-mentioned mode has stable protection effect, the external circuit can react in time and complete circuit disconnection when short circuit and electric leakage occur, but the circuit breaker can be disconnected when any fault occurs in the circuit; therefore, after the circuit breaker trips, a user cannot know the specific tripping reason of the circuit, and the difficulty in troubleshooting the circuit problem is increased. And the solution mode of different circuit problems is different, and when the circuit breaks because of overflowing, the user can reclose and continue to use through the circuit breaker, then can have great potential safety hazard when the electric leakage problem appears, just can continue to use after needing carefully to investigate and solve. Once a user cannot judge a specific trip reason, it is often difficult to select a correct processing mode and make an error decision easily, so that a great potential safety hazard exists.
On the other hand, a circuit board for leakage detection is also required to be arranged in the leakage electromagnetic system, and the circuit board is respectively connected with an L pole wiring board and an N pole wiring board of the outlet end of the circuit breaker; when the circuit board detects the electric leakage problem, the action of the release can be controlled, so that the actuating mechanism is driven to perform linkage to disconnect the moving contact and the static contact, and the electric leakage protection of the circuit breaker is realized. Meanwhile, after the circuit breaker trips, the wire outlet end connected with the circuit board is not in a power-on state any more, namely the circuit board is powered off together with the circuit breaker.
However, in the actual installation process, the problem of reverse connection of the incoming and outgoing lines of the circuit breaker often occurs, namely, an external line is accessed from the outgoing line end, and an internal line is accessed from the incoming line end; and in case the circuit breaker is in the back wiring, then can lead to when the leakage current opens the electric leakage electromagnetic system through the circuit board, the electric leakage electromagnetic system can not break off together along with the tripping operation of circuit breaker, but the work of continuing circular telegram is until burning out to the working life of release has been shortened greatly. If the electromagnetic system is controlled and solved through a circuit board, a single chip microcomputer needs to be additionally arranged for control, so that the price of the electromagnetic system is about 50 times higher than that of the existing structure, and the cost requirement of a manufacturer cannot be met.
In addition, in the current circuit breaker structure, because actuating mechanism and contact system all directly mounted on the circuit breaker casing, lead to the user when installing actuating mechanism and contact system to one of them side, cause the part of opposite side to drop very easily, increased the installation degree of difficulty to the circuit breaker. Moreover, because the functional components are required to be installed by taking the breaker shell as a carrier, all the components in the breaker need to be sequentially installed in multiple processes in the actual installation process; thereby causing an extension of the overall installation process of the circuit breaker and a reduction in production efficiency.
Therefore, the existing bipolar circuit breaker has the problems that the electric leakage problem cannot be displayed, the circuit board cannot be normally powered off and the installation difficulty is large.

When the circuit breaker is disconnected, the levers 14 in the first actuating mechanism 2 and the second actuating mechanism 3 both rotate and drive the moving contact 4 to be separated from the fixed contact, so that tripping of the circuit breaker is realized. And when the moving contact 4 breaks away from the fixed contact, the power-taking spring 19 can not take power from the driven contact spring 18, so that the matching power-off of the circuit board 17 and the circuit breaker is realized, the circuit board 17 is disconnected with the power supply of the leakage electromagnetic system 5 after the power-off, the leakage electromagnetic system 5 can be powered off with the power-off, and the continuous power-on of the leakage electromagnetic system 5 after the circuit breaker is tripped is effectively avoided.
