Abstract
The utility model provides an isolated moving plug for coal mine high-voltage electrical distribution device, which solves technical problems of the hand-trolley isolated moving plug's bulky size, clumsiness, inconvenience for operation and susceptibility to damaging the components wherein. The utility model consists of an isolating frame, bundled moving contact terminals, and an insulating slide shaft. The insulating frame is a support body for the isolated moving plugs. The bundled moving contact terminal consists of contact terminal plate, bundled spring, support frame, conducting rod and insulating board; the insulating slide shaft consists of an insulating shaft and an insulating screw nut; the head of the bundled moving contact terminal consisting of a support frame and a contact terminal plate, is bundled by a tension spring, with every 2 contact terminal plates as a set homogeneously distributed on the support frame. Due to the relatively big gap between the connecting hole of the insulating board and the saddle cover, and that between the insulating board and insulating frame, every moving plug can be moved upward, downwards, leftwards, rightwards, forwards and backwards, therefore the insulating moving plug has self-regulating function and makes the electrical connection more reliable.
Description
Technical field
The utility model relates to a kind of isolated moving plug, and more particularly, it relates to the isolated moving plug of high voltage distribution installation under a kind of coal mine.
Background technology
High voltage distribution installation adopts the handcart-type isolated moving plug that contains components and parts such as circuit breaker, voltage transformer, current transformer and piezo-resistance usually under the coal mine, this handcart-type isolated moving plug, volume is big, heavy, inconvenient operation when branch, combined floodgate, and being easy to damage wherein components and parts, security reliability is not high.
Summary of the invention
The purpose of this utility model provides the isolated moving plug (hereinafter to be referred as isolated moving plug) of high voltage distribution installation under a kind of coal mine, it will bear the plug portion and the components and parts separation cut main circuit powers such as circuit breaker, voltage transformer, current transformer and piezo-resistance of branch, combined floodgate task, solved the handcart-type isolated moving plug, volume is big, heavy, the inconvenience that operates is also damaged wherein components and parts, the technical problem that security reliability is low easily.The utility model is achieved by the following technical programs:
The isolated moving plug of high voltage distribution installation under this coal mine, comprise insulating frame 3 and in its both sides by the fixedly connected slips insulation axle 1 of insulation nut 2, and 3 groups of moving plugs 15 that are distributed on insulating frame 3 fronts, described insulating frame 3 is provided with centre bore 19 and connecting hole 18, be provided with insulation board 4 in the inboard of insulating frame 3, insulation board 4 is provided with centre bore 16 and connecting hole 17, the internal diameter of connecting hole 18 is less than the internal diameter of connecting hole 17, the middle part of insulation board 4 is provided with conducting rod 8, the thin end afterbody of conducting rod 8 is fixed on the insulation board 4 by the copper nut 14 of its end by the centre bore 16 and the insulating frame centre bore 19 of insulation board 4, in the groove of the head of conducting rod 8, be provided with contact blade 7, its inboard is provided with support 6, contact blade 7 is bundled by extension spring 5, in the connecting hole 17 of insulation board 4, be provided with cushion cover 11, the external diameter of cushion cover 11 is littler 3 millimeters and greater than the internal diameter of connecting hole 18 than the internal diameter of connecting hole 17, thereby form gap 12, the thickness of the aspect ratio insulation board 4 of cushion cover 11 is big 1 millimeter, thereby form gap 20, the whole plug part can be moved forward and backward up and down with respect to insulating frame, and bolt 9 is by large washer 10, cushion cover 11 and nut 13 couple together insulation board 4 and insulating frame 3.This isolated moving plug generally is power supplying and distributing equipment high voltage distribution installation and the high volt starter that is used for 10 kilovolts or the 6 kilovolts electric power systems in down-hole.Described contact blade 7 can be per two one group, can be uniform 6 groups in the head groove of each conducting rod 8.The binding extension spring 5 that is provided with on the described contact blade 7 is preferably 4.
It is little to the utlity model has volume, in light weight, it is light to divide, close a floodgate, because between the connecting hole 17 of insulation board 4 and the cushion cover and all gapped between insulation board and the insulating frame, make each plug device can center on its central movable, therefore this plug has possessed autoregulation, and it is more reliable that it is electrically connected.
