The residual current operated circuit-breaker comprises an electronic circuit board, a zero sequence mutual inductor, and an electrical leakage release, wherein the electronic circuit board comprises a power strip for obtaining power supply from breaker three phase and a signal plate for outputting release signals to the electrical leakage release; a first film cable is connected between the power strip and the signal plate; the central section of the first film cable is provided with a jack; the first film cable is plugged with the pre-embedded row needles of the zero sequence mutual inductor via the jack and is connected with the pre-embedded row needles in a welding mode; the output terminal of the signal plate is connected with a second film cable; the input terminal of the electric leakage release is provided with a film cable plugging port; and the end portion of the second film cable is connected with the film cable plugging port via plugging. The residual current operated circuit-breaker of the utility model features simple structure, convenient manufacturing and installation, and reliable line connection.
Description
Technical field
The utility model belongs to low voltage power transmission equipment, relates 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; provide protection to shock hazard simultaneously, can also be to providing supplementary protection because overcurrent protective device can not detected and long-standing earth fault may cause fire hazard and other danger.
Existing residual current action breaker is comprised of breaker body part and electronic unit.Electronic unit comprises that zero-sequence transformer, electronic circuit board, magnet ring wire and leakage tripping device form.Get three-phase current by the magnet ring wire, the residual current in the zero-sequence transformer detection line, and by leakage tripping device action realization residual current protecting.Because the circuit breaker space is little; and need magnet ring wire, electronic circuit board and leakage tripping device are connected with wire; and be assemblied in the space of less; so higher to the matching requirements of electronic unit part; so if cabling is in disorder or assemble the improper circuit breaker phase fault that causes easily; even the danger of burning, thereby can't realize residual current protecting.
Summary of the invention
The technical problems to be solved in the utility model provide a kind of simple in structure, make residual current action breaker easy for installation, the reliable grout cable structure of connection.
The residual current action breaker of grout cable structure of the present utility model includes electronic circuit board, zero-sequence transformer and the leakage tripping device that is installed in the Shell of circuit breaker; Described electronic circuit board includes to obtain the power panel of power supply and be used for to the signal plate of release output trip signal from the circuit breaker three-phase, be connected with the first film cable between power panel and the signal plate, the first film cable middle part is provided with jack, and the first film cable connects and is welded to connect by pre-buried row's cushion of jack and zero-sequence transformer; 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 the electronic circuit board is connected to the circuit breaker three-phase nearby, again with the grout cable of electronic circuit board and row's pin welding of zero-sequence transformer, at last the grout cable on the electronic circuit board is connected to the working method on the leakage tripping device, connection between each parts is simple, convenient, and reliable, reduce the requirement to product manufacturing and installation, improved the reliability of residual current acting.
