Description
Technical Field
The invention belongs to the technical field of piezoelectric devices, and particularly relates to a circuit breaker with an interlocking shaft position signal output function.
Background
The low-voltage frame breaker is a low-voltage electrical equipment component with larger capacity, is mainly used in industrial electrical systems, can ensure the connection and disconnection of a circuit under rated load, can automatically disconnect the circuit under abnormal conditions (such as overload, short circuit, undervoltage and the like) of the circuit, and can completely isolate the load from a power supply by separating a movable contact and a static contact.
Normal operation of a circuit breaker is critical to a power system, and once the circuit breaker fails, the power system often needs to be suspended for maintenance, thus causing a large loss. In order to ensure the normal use of the circuit breaker, the working states of a plurality of functional modules in the circuit breaker need to be monitored, and the circuit breaker can be processed in time once abnormality is found. The inability to close is one of typical faults of a circuit breaker, and because of the large number of parts and functional modules such as an operating mechanism, a transmission structure, a closing electromagnet, a shunt release, an undervoltage release and the like, the specific position of the fault is not easy to find in a short time. In general, the reasons why a circuit breaker cannot be closed are as follows: the trip signal of the trip unit is not reset (i.e., the "reset" button on the housing is not pressed); the energy storage of the operating mechanism is not in place; the closing coil is not electrified; the switching-off coil is in an electrified state; the undervoltage coil is not electrified; the position of the interlocking shaft is inaccurate; the linkage system inside the operating mechanism fails.
In the prior art, the working states of a tripping signal, a closing coil, a separating coil and an undervoltage coil of a tripping device in a circuit breaker can be monitored in real time, but the state of an interlocking shaft cannot be monitored. The interlocking shaft is placed in a groove of the base and can rotate, the end of the interlocking shaft is in contact with the end of the brake separating half shaft in the operating mechanism, and when the end of the interlocking shaft, which is positioned outside the circuit breaker, is driven by external force to rotate the interlocking shaft, the brake separating half shaft can be driven to rotate to perform brake separating operation on the operating mechanism. When the breaker fails and can not be switched on, the prior art is adopted, whether the tripping signal of the tripping device is reset or not can be checked from the upper computer, whether the energy storage signal of the operating mechanism is normal or not can be determined by checking the state signals of the switching-on coil, the switching-off coil and the undervoltage coil, but because the state of the interlocking shaft can not be monitored, the on-site check is needed by manpower, and whether the position of the interlocking shaft is accurate or not is determined. If the position of the interlocking shaft is inaccurate, the interlocking shaft may drive the brake-separating half shaft to be in a brake-separating position, so that the operating mechanism cannot perform a brake-closing operation. The process of checking the interlocking shaft on site needs to disassemble the shell of the circuit breaker and part of internal accessories (such as a shunt release, a closed electromagnet, an undervoltage release and the like), so that the overhaul time of the circuit breaker is greatly increased, the overhaul cost is increased, and in addition, under the condition of not definitely specifying the specific fault position, the checking process has a larger risk for operators.
