Abstract
The utility model discloses a kind of two tunnel clearance interlocking power switches, comprise two switching device first switching devices and second switch device, two described switching devices comprise incoming line and line outlet respectively, the line outlet of the first described switching device is connected by the line outlet of wire with described second switch device, connect for being linked in sequence between it, first switch and second switch device are provided with switch, switch on two switching devices is oppositely arranged each other, and the switch on two switching devices is linked together by a switch plunger.Two tunnel break-make interlocking power switches of the present utility model, structure is simple, easy to operate, achieves the interlock function between two switches.Avoid two road power supplys to produce the generation of short circuit phenomenon completely, provide the guarantee on equipment for safety operation.
Description
Technical field
The utility model relates to a kind of switch, particularly a kind of two tunnel break-make interlocking power switches.
Background technology
Only has independent on-off switch in the market, a switch can only control the break-make of a road power supply, when must ensure at some special occasions power consumption equipments can not power-off, when needing two road Power supplies, two road power supplys can only be controlled respectively at present with two independent on-off switches, Er Zhe bis-road power supply can not be served again simultaneously, a road power supply necessarily can only be had to connect, and another road power supply must disconnect; And independent two disconnects can not realize linkage interlocked function, the possibility of misoperation may be produced when operating, two road power supplys can not be avoided completely to produce the generation of short circuit phenomenons.
Utility model content
The purpose of this utility model is for solving the problem, and provides a kind of two tunnel break-make interlocking power switches.
In order to achieve the above object, the utility model provides following technical scheme: a kind of two tunnel clearance interlocking power switches, comprise two switching device first switching devices and second switch device, two described switching devices comprise incoming line and line outlet respectively, the line outlet of the first described switching device is connected by the line outlet of wire with described second switch device, connect for being linked in sequence between it, first switch and second switch device are provided with switch, switch on two switching devices is oppositely arranged each other, switch on two switching devices is linked together by a switch plunger.
Beneficial effect:
Two tunnel break-make interlocking power switches of the present utility model, structure is simple, easy to operate, achieves the interlock function between two switches.Avoid two road power supplys to produce the generation of short circuit phenomenon completely, provide the guarantee on equipment for safety operation.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is circuit theory diagrams of the present utility model.
Embodiment
Below with reference to specific embodiment, the technical scheme that the utility model provides is described in detail, following embodiment should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model.
One two tunnel clearance interlocking power switch as shown in Figure 1, comprise two switching device first switching devices 1 and second switch device 5, two described switching devices comprise incoming line and line outlet respectively, the line outlet of the first described switching device 1 is connected by the line outlet of wire with described second switch device 5, connect for being linked in sequence between it, namely the line outlet of L1 is connected to the line outlet of L2, the line outlet of N1 is connected to the line outlet of N2, L1, N1 and L2, the incoming line of N2 connects two different power supplys respectively, L2 is connected to by electric loading, the line outlet of N2.
First switching device 1 with second switch device 5 are provided with switch, and the switch be respectively on switch 2 and switch 4, two switching devices is oppositely arranged each other, and the switch on two switching devices is linked together by a switch plunger 3.When push rod upwards boosts, switch 2 and switch 4 are all upwards beat, and now the incoming line of a switching device and line outlet are connected, and the incoming line of another switching device and line outlet disconnect, and make two switching devices can only have a connection.
Be illustrated in figure 2 circuit theory diagrams of the present utility model, can find out that its operation principle is: when having L1, L2 bis-road Power supply, when switch is up beaten, the M1 closing of contact in figure, M2 contact disconnects, L1 road Power supply; When switch is down beaten, the M2 closing of contact, M1 contact disconnects, L2 road Power supply; This device ensure that power consumption equipment can only have a road power supply to power to power consumption equipment, can not produce the generation of the short circuit phenomenon between two road power supplys because of artificial misoperation.
The utility model is applicable to connecing three phase mains equally and uses.
Two tunnel break-make interlocking power switching manipulations of the present utility model are convenient, the function of two switches, merge into a switch and use, convenient operation.Achieve the interlock function between two switches.Two road power supplys are avoided to produce the generation of short circuit phenomenon completely.The present invention is the guarantee that safety operation provides on equipment.
Technological means disclosed in the utility model scheme is not limited only to the technological means disclosed in above-mentioned execution mode; also comprise the technical scheme be made up of above technical characteristic combination in any; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection range of the present utility model.
