Abstract
The utility model discloses a simple low-voltage switching device for rapid repair in the technical field of power supply and distribution, and aims at solving a problem that a power supply system cannot supply power timely in the prior art because of the replacement of a circuit breaker. The device comprises a door plate and the circuit breaker embedded in the door plate. The wire inlet and outlet ends of the circuit breaker are respectively connected with a connecting cable. The free ends of the connecting cables are respectively connected with a cable plug. When the device is in operation, the cable plugs from the circuit breaker are respectively plugged at two ends of a to-be-overhauled circuit, and a control switch is switched to an opening state, thereby completing the operation of rapid overhaul. The device is simple in structure, is convenient to operate, can replace a low-voltage circuit breaker temporarily during the rapid repair of the power supply system, and shortens the power-off time.
Description
Technical field
The utility model relates to a kind of low voltage switching device, particularly a kind of simple and fast repairing low voltage switching device.
Background technology
Low-voltage circuit breaker claims again automatic switch, and it is a kind of existing hand switch effect, can automatically carry out again decompression, under-voltage, overload and the electrical equipment of short-circuit protection.It can be used to distribute electric energy; do not start continually asynchronous motor; power circuit and motor etc. are carried out to protection, can automatic shutdown circuit when serious overload or short circuit and the fault such as under-voltage occur for they, its function is equivalent to Fuse switch and the combination of crossing underheat relay etc.
Its weak point is: when low-voltage circuit breaker damages, if job site is without the low-voltage circuit breaker of model coupling, cannot realize supply line's rapid rush-repair, this is for not allowing a stage load user and the two stage load users of long-time power failure certainly will cause serious adverse consequences.
Utility model content
The purpose of this utility model is to provide a kind of simple and fast repairing low voltage switching device, and Ke supply line is used as interim circuit breaker during rapid rush-repair, shortens the power failure time.
The purpose of this utility model is achieved in that simple and fast repairing low voltage switching device, comprise door-plate and be flush-mounted in the circuit breaker on door-plate, the end of incoming cables of described circuit breaker and leading-out terminal are connected with respectively stube cable, and the free end of described stube cable is all connected with cable plug.
Compared with prior art, the beneficial effects of the utility model are: during work, the cable plug of drawing from circuit breaker is plugged to respectively to the two ends of Awaiting Overhaul circuit, control switch is allocated to open mode, complete Quick overhaul work, it is simple in structure, easy to operate, can when electric power system rapid rush-repair, replace low-voltage circuit breaker temporarily and use, and shortens the power failure time.
As further improvement of the utility model, the two ends of described door-plate are respectively equipped with handle.Handle is set on door-plate makes operation construct more convenient and be easy to carry about with one.
As further improvement of the utility model, the indicator light that is used to indicate connecting and disconnecting of the circuit is also installed on described door-plate.Indicator light is lighted, and represents that Awaiting Overhaul circuit is communicated with.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is that the A of Fig. 1 is to view.
Fig. 3 is the stereogram of Fig. 1.
Wherein, 1 door-plate; 2 circuit breakers; 3 stube cables; 4 cable plugs; 5 handles; 6 indicator lights.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As Figure 1-3, for simple and fast repairing low voltage switching device, comprise door-plate 1 and be flush-mounted in the circuit breaker 2 on door-plate 1, the end of incoming cables of circuit breaker 2 and leading-out terminal are connected with respectively stube cable 3, and the free end of stube cable 3 is all connected with cable plug 4.For the ease of carrying and installation, the two ends of door-plate 1 are respectively equipped with handle 5, and the indicator light 6 that is used to indicate connecting and disconnecting of the circuit is also installed on door-plate 1.
The utility model is not limited to above-described embodiment; on the basis of the disclosed technical scheme of the utility model; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some replacements and distortion to some technical characterictics wherein, these replacements and distortion are all in protection range of the present utility model.
