Abstract
The utility model relates to a mine explosion-proof multifunctional vacuum reversible portable switch, which comprises a reversing switch, an electronic protector, vacuum contactors, etc. The utility model is characterized in that coupled angle plates 16, 19 are respectively arranged below moving contacts 14, 12 on the vacuum contactors 1, 2; the opposite lower parts of the angle plates 16, 19 are connected through a pin; a gasket 18 is sheathed on the pin between the angle pates 16, 19. The device structure has the advantages of simple structure, convenient manufacture, installation, regulating and maintenance. In use, the utility model has excellent operational reliability and ensures the disconnection of the other side moving contact when moving contact on one side is attracted to close.
Description
The utility model relates to a kind of mining portable switch, exactly is the reversible portable switch of flame-proof mine multifunctional vacuum.
Existing mine vacuum reversible switch uses in the application in reality, requires i.e. two vacuum contactors of its core component, no matter when do not allow it to move simultaneously.Therefore, when making, must be provided with a mechanism between them and finish necessary mechanical latching and electric blocking.Electric blocking is carried out quite convenient, and mechanical latching implements then difficulty relatively.The existing mechanical blocking mechanism is such, promptly is respectively equipped with the pressing plate of moving contact and interlock at the opposite side of two vacuum contactors by rotating shaft, connects with a drive link between two vacuum contactors again, realizes mechanical latching.But, this mechanism in actual applications, on the one hand functional reliability is poor, sometimes, after a side moving contact and the vacuum contactor adhesive, the opposite side moving contact is also failed and another vacuum contactor disconnection; Debug difficulties in using on the other hand needs countershaft to change, and makes troubles to use.
The purpose of this utility model is: provide in a kind of use and debug conveniently, mechanical latching switches the reversible portable switch of reliable mine vacuum.
The technical solution that realizes above-mentioned purpose is such.
The reversible portable switch of flame-proof mine multifunctional vacuum, comprise reversing switch, current transformer, capacitance-resistance adhesive element, transformer, electronic protector, fuse and vacuum contactor etc., it is characterized in that: moving contact 14 belows are provided with the gusset 16 of interlock on the vacuum contactor 1; Moving contact 12 belows are provided with the gusset 19 of interlock on the relative vacuum contactor 2; Gusset 16,19 relative bottoms connect by pin, are arranged with packing ring 18 on the pin between the gusset 16,19.
The mechanical lock that the utility model adopts, simple in structure, make, install, debug, safeguard all very convenient; In the use, when a side vacuum contactor and moving contact adhesive, can guarantee that opposite side vacuum contactor and moving contact disconnect, and have the good operation reliability.
Fig. 1 is the utility model structural front view,
Fig. 2 is the vertical view of Fig. 1.
Below in conjunction with accompanying drawing, the utility model is described further by embodiment.
The reversible portable switch of this flame-proof mine multifunctional vacuum comprises reversing switch, current transformer, capacitance-resistance adhesive element, transformer, electronic protector, fuse and two vacuum contactors etc.As seen from Figure 1, be mechanical lock between two vacuum contactors 1,2.This mechanical lock comprises moving contact 14,12, pressing plate 15,13, connecting plate 3,4,5 between the moving contact and gusset 16,19 etc.Gusset 16,19 is fixedly mounted on moving contact 14,12 bottoms respectively, and two gusset bottoms are corresponding: when moving contact 14 rotates around axle 20, or moving contact 12 is when axle 21 rotates, and gusset 16 or 19 is also done corresponding rotation.Two gussets, 16,19 corresponding bottoms are fixedly connected by pin 17, and suit packing ring 18 on the pin 17 between two gussets.
As seen from Figure 2, connecting plate 3,4,5 connects the secondary side of reversing switch; Termination 6 and termination 9 short circuits, termination 8 and termination 10 short circuits connect the controlled device of reversible switch behind termination 7 and termination 11 short circuits.
In the use, after 1 energising of vacuum contactor, moving contact 14 is the center with the pressing plate 15 that links to each other with axle 20, overcomes the spring force of self, rotates counterclockwise and adhesive, drives gusset 16 motions simultaneously, and gusset 16 is against gusset 19 1 sides tightly with packing ring 18.At this moment, electric even vacuum contactor 2 gets, also can not adhesive.
When 1 outage of vacuum contactor, after vacuum contactor 2 energisings, moving contact 12 clockwise rotates and adhesive, the same gusset 19 that drives moves, and is the center with axle 21, overcomes the spring force of self, clockwise direction rotates, and gusset 19 is against gusset 16 1 sides tightly with packing ring 18.At this moment, it is electric that vacuum contactor 1 was got, also can not adhesive.
