The remote simulation electric leakage device mainly comprises a casing, an upper cover body, a button internal wire and an ingoing line compressing device; three binding posts are fixed on the casing; a horn mouth can be screwed into the casing through a screw socket; three explosion-proof button elements penetrate through the upper cover and are fixed on the upper cover; buttons of the upper cover can be pressed down to touch normally-opened contact points of the explosion-proof button elements below the upper cover; the upper cover is fixed with the casing by bolts; after fixation, no clearance is reserved between the upper cover and the explosion-proof surface of the casing; a cable is introduced from the horn mouth and enters the casing through a rubber sealing ring; three phase lines are respectively connected with the normally-opened contact points of the three explosion-proof buttons; a cable grounding line enters the casing and is then connected to the special binding post and is connected with one end of a resistor; and the other end of the resistor is connected with the other ends of the normally-opened contact points of the three explosion-proof buttons. The device is simple in operation and reliable in running and has low cost.
Description
Technical field
The utility model relates to a kind of simulation electric leakage device, a specifically a kind of distant place, down-hole, mine manual simulation's electric leakage device that is suitable for containing damp (methane) and coal dust.
Background technology
Earth leakage protective is one of three big protections of colliery electric power system, in 455 regulations of " safety regulations in coal mine " version in 2010: on the feed line that the down-hole is drawn by working section sub station, mobile substation or distributor point, should install short circuit, overload and earth leakage protective device.Article 457, regulation also: on the low voltage feeder line of down-hole, must installing leak detection protective device or earth leakage protective device selectively, guarantee to cut off automatically the feeder line of electric leakage; Must carry out a trip test every day to the ruuning situation of low pressure leakage detection apparatus.
The 19th regulation of " installation, operation, maintenance and the maintenance detailed rules and regulations of low pressure leak detection protective device under the coal mine " that the former coal Ministry of Industry formulates: operating leak detection protective device, did the artificial leakage tripping in a distant place at least and test in every month.
This concrete grammar that has also provided the artificial leakage tripping test in a distant place simultaneously is: (127v is with 2k Ω, 10w resistance to insert test resistances in the load side of the control switch of distal-most end by different low pressure grades; 380v 3.5k Ω, 10w resistance; 660v 11k Ω, 10w resistance; 1140v 20k Ω, 10w resistance; ) as in the electromagnetic starter (switch), test resistance one terminates on the screw socket of fuse tube, whether the other end is connected on the shell, send electricity after covering shell, observe feeding switch and trip.If tripping operation illustrates leak detection protective device reliable in action.After test finishes, remove test resistance.
In the actual use in colliery, feeding switch usually reaches the distance of km apart from the distance of magnetic starter.
The experimental technique that " detailed rules and regulations " provide is also being continued to use at present.This method has following shortcoming:
1, inconvenience, each experiment all need be uncapped;
2, the interior various devices of switch are more at present, as the capacitor and inductor element, after uncapping, if these elements can not have been put the electric charge of depositing, the operator got shocked; Heavy then for highly gassy mine, gas or coal dust can ignite.
Summary of the invention
The purpose of this utility model provides an a kind of distant place, down-hole, mine manual simulation's electric leakage device safe, reliable, simple to operate that has.
The utility model mainly is made up of housing, upper cover body, button back panel wiring and inlet wire hold down gag, three binding posts are fixed on the housing, horn mouth can be screwed into housing by screw socket, three explosion-proof button elements pass loam cake, and are fixed on and cover, and the button of loam cake can be pressed, touch the normal opened contact of the explosion-proof button element under the loam cake, loam cake and housing are by bolt, and after fixing, explosion-proof of loam cake and housing keeps no gap; Cable is introduced from horn mouth, and in rubber seal entered housing, three phase lines connect the normal opened contact of three explosion-proof buttons respectively, after the cable grounding line enters housing, is connected on the special-purpose binding post, is connected with an end of resistance again; The other end of resistance is connected with the other end of the normal opened contact of three explosion-proof buttons.
The utility model has following advantage compared with prior art:
The utlity model has simple, practical characteristics.Also meet the requirement of relevant criterion such as GB3836.1-2000, GB3836.2-2000, MT624-1996, Q/DF48-2006 simultaneously.Be applicable under the coal mine that contains damp (methane) and coal dust.Process of the test is easy, and is simple to operate, reliable, and cost is low; Be highly suitable for containing under the coal mine of damp (methane) and coal dust.
This device integral body is composite structured, and shell adopts the INCREASEDSAFETY structure, has stronger waterproof, dirt exclusion capabilities.Interior dress explosion-proof button.

Among the figure: 1. housing; 2. loam cake; 3. button; 4. explosion-proof button element; 5. bolt; 6. explosion-proof; 7. normal opened contact; 8. phase line; 9. binding post; 10. resistance; 11. cable grounding line; 12. rubber seal; 13. horn mouth; 14. cable.
Embodiment
Further specify the utility model below in conjunction with accompanying drawing.
The utility model mainly is made up of housing 1, loam cake 2, button back panel wiring and inlet wire hold down gag, three binding posts 9 are fixed on the housing 1, horn mouth 13 can be screwed into housing 1 by screw socket, three explosion-proof button elements 4 pass loam cake 2, and are fixed on the loam cake 2, and the button 3 of loam cake 2 can be pressed, touch the normal opened contact 7 of the explosion-proof button element 4 under the loam cake 2, loam cake 2 is fixing by bolt 5 with housing 1, and after fixing, explosion-proof 6 of loam cake 2 and housing 1 keeps no gap; Cable 14 is introduced from horn mouth 13, and in rubber seal 12 entered housing 1, three phase lines 8 connect the normal opened contact 7 of three explosion-proof buttons respectively, after cable grounding line 11 enters housing 1, were connected on the special-purpose binding post, were connected with an end of resistance 10 again; The other end of resistance 10 is connected with the other end of the normal opened contact 7 of three explosion-proof buttons.
The whole blast resistance construction of this device is identical with existing flame-proof mine control button, and just back panel wiring changes.
The operation principle explanation:
This device is along with magnetic starter moves, when needs are done a distant place artificial leakage tripping test, can press any one of A or B or C three-phase button 3 as required, then test resistance is connected between phase line and the ground wire, has so just reached the purpose of distant place manual simulation's leakage tripping test.
