Abstract
The utility model belongs to a coal mine underground production facility, in particular to a mine explosion suppression and intrinsic safety vacuum composite switch, solving the problem of current technology that the multi loop composite switch is mainly composed of a 4 or 6 loop and the electric appliance elements are arranged in one explosion suppression tank. The utility model comprises a portal tank and an electric appliance element positioned in the portal tank; wherein the portal tank at least comprises a plurality of unit tanks, while each unit tank is provided with two loop circuit elements; and two adjacent unit tanks are connected through a flange; and the unit tank is provided with two to four sets; and the portal is provided with a door opening mechanism at the lower part. Compared with the prior art the utility model has the advantages of that: 1. the loop number can be flexibly set to conveniently realize random combination of 2, 4, 6, and 8 loops; 2. during the production practice, two loops in an unit tank are used as the standby by the spare loops, and then the normal operation can not be influenced by the standby loops when carrying out power failure overhauling.
Description
Technical field
The utility model belongs to the underground mine use production equipment, specifically is a kind of mine flameproof and intrinsic safety type vacuum combination switch.
Background technology
Along with the raising of production technology under the coal mine, high-power coal excavation apparatus increases year by year, the corresponding quickening of the update of equipment.The control panel of many large-scale coal-cutting machineries, the single loop electric-controlled switch by original is replaced by multiloop unit switch.Multi-loop combined switch is widely used at present, and manufacturer is also more, and its common characteristic is: 1, the combined loop number is based on 4 or 6 loops; 2, the electric elements in all loops all are assembled in the flameproof cabinet.
Summary of the invention
The utility model is in order to solve in the prior art multi-loop combined switch based on 4 or 6 feeder numbers, and its electric elements all are contained in the problem in the flameproof cabinet, and a kind of mine flameproof and intrinsic safety type vacuum combination switch of realizing 2,4,6,8 loop combination in any is provided.
The utility model adopts following technical scheme to realize: mine flameproof and intrinsic safety type vacuum combination switch comprises the casing that is provided with a body and the electric elements of interior setting thereof.Casing is made up of at least one group of unit box, and two loop electric elements are set in each unit box.Connect by flange between the adjacent cells casing.Unit box is provided with 2～4 groups.Door body below is provided with door-opening mechanism.
Unique body structure form is the packet type switch casing with a required feeder number of user of 2～4 groups of unit box splicings becoming, because of device two circuit controls electrical equipment in each unit box, according to the needed feeder number of user, again several unit boxs independently are stitched together, constitute the unit switch of required feeder number.If the user needs 4 loops, splice two casings and get final product, if the user needs 6 loops, splice 3 casings, if the user needs 8 loops, splice 4 casings.
The utility model beneficial effect compared with prior art is: but 1, the feeder number flexible configuration, realize feeder number combination in any such as 2,4,6,8 easily; 2, in the production practices, back-up circuit can be made standby of two loops in the unit box, does not influence the normal operation in other loop when again back-up circuit being made interruption maintenance.
