Abstract
The utility model discloses an air circuit breaker which comprises a shell and a transformer. The outside of the shell is provided with a groove. The transformer is arranged in the groove and forms an integral structure with the shell. The integral structure comprises a moving contact bus-bar, a wire outlet bus-bar and the groove. The bottom of the groove is provided with a hole. The moving contact bus-bar passes through the hole at the bottom of the groove and is fixedly arranged in the groove. The transformer is provided with a hole. The wire outlet bus-bar and the moving contact bus-bar are connected. The connector of the moving contact bus-bar and the wire outlet bus-bar passes through the hole in the transformer. The transformer and the shell are fixed by the wire outlet bus-bar. The transformer and the shell are fixed by a screw. The air circuit breaker of the utility model has a simple and reasonable structure and is convenient to install and disassemble. By adopting the structure, convenient replacement can be achieved as required by removing the wire outlet bus-bar.
Description
Technical field
The utility model relates to a kind of air circuit, more specifically, relates to a kind of housing and instrument transformer of air circuit.
Background technology
Air circuit, has another name called air switch, is a kind of of circuit breaker.Air circuit is a kind of as long as electric current surpasses the switch that rated current will disconnect automatically in circuit.Air switch is very important a kind of electrical equipment in low voltage power distribution network and electric drive system, and it integrates controls and multi-protective function.Decapacitation completes outside contact and minute deenergizing, and the short circuit that still can occur circuit or electric equipment, seriously overload and under voltage etc. are protected, and the while also can be for actuating motor continually not.
According to different application scenario circuit breakers, divided again different frame sizes, and the circuit breaker of same shell frame can be set different rated current.Because rated current spans different under same shell frame may be very large, in order to guarantee precision, under same shell frame, the circuit breaker of different rated current may need different instrument transformers.
The instrument transformer of traditional air circuit is placed in Shell of circuit breaker inside, during replacing, housing need to be taken apart and could be changed, and wastes time and energy.
Utility model content
The shortcoming wasting time and energy in order to overcome the unloading process that exists in prior art, the utility model provide a kind of instrument transformer simple and reasonable, remove and install air circuit easily.
The technical solution adopted in the utility model is:
An air circuit, comprises housing and instrument transformer, and described outside is provided with groove, and described instrument transformer is arranged in groove, forms an overall structure with housing.
As further improvement of the utility model, described overall structure comprises movable contact bus bar, outgoing line busbar and groove, described bottom portion of groove is provided with hole, described movable contact bus bar is through the hole of bottom portion of groove, be fixedly installed in groove, described instrument transformer is provided with a hole, and described outgoing line busbar is connected with movable contact bus bar, the connector of movable contact bus bar and outgoing line busbar is through the hole on instrument transformer, and described instrument transformer and housing are fixed by outgoing line busbar.
As further improvement of the utility model, described instrument transformer and housing are fixed by screw.
The beneficial effects of the utility model are:
A kind of air circuit of the utility model is simple and reasonable, remove and install conveniently, adopts after said structure, when needs are changed dismounting, only need pull down outgoing line busbar, can realize and being convenient for changing.
Accompanying drawing explanation
Fig. 1 is the instrument transformer scheme of installation of a kind of air circuit of the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
An air circuit, comprises housing 1 and instrument transformer 3, and housing 1 outer setting is fluted 5, and instrument transformer 3 is arranged in groove 5, forms an overall structure with housing 1.
Instrument transformer 3 can directly be fixed by outgoing line busbar 4 with housing 1: overall structure comprises movable contact bus bar 2, outgoing line busbar 4 and groove 5, groove 5 bottoms are provided with hole, movable contact bus bar 2 is through the hole of groove 5 bottoms, be fixedly installed in groove 5, instrument transformer 3 is provided with a hole, outgoing line busbar 4 is connected with movable contact bus bar 2, and the connector of movable contact bus bar 2 and outgoing line busbar 4 is through the hole on instrument transformer 3.
The concrete structure that the purpose of this utility model is achieved in that air circuit as shown in Figure 1, comprises housing 1, movable contact bus bar 2, instrument transformer 3, outgoing line busbar 4, and housing 1 is outside fluted, and bottom portion of groove has a circular hole; Movable contact bus bar 2 is through the circular hole of housing 1 bottom portion of groove; Outgoing line busbar 4 is connected with movable contact bus bar 2; Instrument transformer 3 has a hole, instrument transformer is placed in housing 1 groove and forms an integral body with housing, the connector of movable contact bus bar 2 and outgoing line busbar 4 is through the hole of instrument transformer 3, and instrument transformer 3 can be fixed by screws on housing, also can be fixed on housing by outgoing line busbar 4.
A kind of air circuit of the utility model, directly assembles instrument transformer 3 and housing 1, therefore adopts after said structure, when needs are changed dismounting, only need pull down outgoing line busbar 4, can realize replacing.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model.All any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
