Description
Technical field
The invention belongs to low voltage power transmission equipment, relate to a kind of residual current action breaker of grout cable structure.
Background technology
Residual current action breaker has overload, short circuit and under-voltage protection function; energy protection circuit and power-supply device are not damaged; there is provided protection to shock hazard simultaneously, can also to can not detect due to overcurrent protective device and long-standing earth fault may cause fire hazard and other danger to provide supplementary protection.
Existing residual current action breaker is made up of breaker body part and electronic unit.Electronic unit comprises zero-sequence transformer, electronic circuit board, magnet ring wire and leakage tripping device composition.Get three-phase current by magnet ring wire, the residual current in zero-sequence transformer detection line, and realize residual current protecting by leakage tripping device action.Because circuit breaker space is little; and magnet ring wire, electronic circuit board and leakage tripping device wire need be connected; and be assemblied in relatively little space; therefore it is higher to electronic component portions matching requirements; if so cabling is in disorder or assemble and improperly easily cause circuit breaker phase fault; the danger of even burning, thus cannot residual current protecting be realized.
Summary of the invention
The technical problem to be solved in the present invention is to provide that a kind of structure is simple, making and installation is convenient, the residual current action breaker of the reliable grout cable structure of connection.
The residual current action breaker of grout cable structure of the present invention includes the electronic circuit board be arranged in Shell of circuit breaker, zero-sequence transformer and leakage tripping device; Described electronic circuit board includes for obtaining the power panel of power supply from circuit breaker three-phase and being used for exporting to release the signal plate of trip signal, the first film cable is connected with between power panel and signal plate, be provided with jack in the middle part of the first film cable, the first film cable is connect by pre-buried row's cushion of jack and zero-sequence transformer and is welded to connect; The output of described signal plate is connected with the second grout cable, and the input of described leakage tripping device is provided with a grout cable interface, the second grout cable end and the socket connection of grout cable interface.
After adopting above-mentioned structure, power taking line on electronic circuit board is connected to circuit breaker three-phase nearby, again the grout cable of electronic circuit board is welded with row's pin of zero-sequence transformer, finally the grout cable on electronic circuit board is connected to the working method on leakage tripping device, connection between each parts is simple, convenient, and reliable, reduce the requirement to product manufacturing and installation, improve the reliability of residual current acting.
