Abstract
A casing of a reactive power compensator and an explosion isolating vacuum feeder switch for a mine comprises a casing body formed by a left front door, a right front door and a left lateral door. A wiring box is arranged above a right front door, a control line terminal is arranged in front of the wiring box, a cable inlet terminal is arranged at the back of the wiring box, a cable outlet terminal is arranged on the right of the wiring box, a wiring box cover is arranged above the wiring box, a power line wiring terminal, and a load wiring terminal and the control line wiring terminal are arranged on the wiring box cover. An electrical control unit is effectively divided into two parts: the vacuum feeder switch and the reactive power compensator unit. The casing with the structure is adopted so that the vacuum feeder switch and the reactive power compensator unit enter the casing body through the left lateral door and the right front door respectively during installation, thereby being convenient. In debugging and maintenance, the left front door can be opened. The cable is led in from the back and led out from the right, thereby reducing volume of the casing and facilitating underground transportation and placement.
Description
Technical field
The utility model belongs to power system automatic field, is specifically related to a kind of flame-proof mine vacuum feed switch and reactive power compensator shell.
Background technology
Along with the further transformation of Coal Production, high-power coal mining, driving, transporting equipment strengthen in the underground mine use amount.These equipment all are inductive loads, arrange that at a working face cause underground mine use electrical power factor low, waste of energy is serious.Flame-proof mine vacuum feed switch and reactive power compensator through electrical network input and excision capacitor are improved power factor of electric network, reduce waste of energy to these shortcoming designs.But the structure that the shell of present flame-proof mine vacuum feed switch and reactive power compensator adopts is: two or three doors of equipment front, and electric control unit is packed into from the front; The introducing of cable and the both sides of drawing apportion equipment.This structural design is reasonable inadequately, makes electric control unit be divided into scattered several parts, is not easy to maintenance and debugging, and is unfavorable to electrical network input and excision capacitor raising power factor of electric network.The cable of this structure need pass in and out about apportion simultaneously, the body that must extend, but receive the restriction of colliery underworkings, so be not easy to the down-hole transportation.
The utility model content
The utility model technical problem to be solved rationally makes electric control unit be divided into scattered, problem such as be not easy to keep in repair and debug inadequately to layout in the prior art a kind of rationally distributed, flame-proof mine vacuum feed switch and reactive power compensator shell that debugging is easy to maintenance is provided.
For the technical problem that solves the utility model is taked following technical scheme:
A kind of flame-proof mine vacuum feed switch and reactive power compensator shell; Comprise the body of being made up of left front door, right front door, offside door, a junction box is installed in said right front door top, and said junction box's front is provided with the control line terminal; Said junction box's back is provided with the cable leading-in terminal; Said junction box's the right side is provided with the cable leading-out terminal, and the wiring case lid is set above the junction box, and said junction box covers power line terminal, load wiring terminal and control line binding post are set.
The utility model adopts the right front door top of the body of being made up of left front door, right front door, offside door that one junction box is installed, with electric electric control unit effectively branch for two parts: 1. 2. reactive power compensation unit of vacuum feed switch.Adopt the shell of this structure simultaneously, reactive power compensation unit and vacuum feed switch get into body from offside door, right front door respectively during installation, and be very convenient; Can open left front door when adopting debugging, maintenance; Cable is drawn from rear side introducing, right side, has reduced the volume of shell, is convenient to the down-hole transportation and places.

Embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation
A kind of flame-proof mine vacuum feed switch and reactive power compensator shell comprise the body of being made up of left front door 2, right front door 8, junction box 6, offside door 22 1.Body 1 is formed by steel plate and flange assembly welding, and offside door 22, left front door 2, junction box 6, right front door 8 and body 1 are connected through bolted.Junction box 6 is installed in body 1 upper right corner; Be positioned at right front door 8 upper ends, junction box 6 back is provided with cable leading-in terminal 13, and junction box 6 the right side is provided with cable leading-out terminal 9; Power line terminal 14 is set, load wiring terminal 12 and control line binding post 11 above the junction box 6.Junction box 6 front is provided with control line terminal 7; Cable leading-in terminal 13 links to each other with power line terminal 14, and load wiring terminal 12 links to each other with cable leading-out terminal 9.Wiring case lid 23 is set above the junction box 6.
Before the equipment work; Power supply is passed through cable 13 introducings from higher level's power supply unit from the cable leading-in terminal; Be communicated with power line terminal 14, reactive power compensation unit 15 is connected with power line terminal 14 through lead with vacuum feed switch ECU 10, through vacuum feed switch ECU 10 control load binding posts 12; The load wiring terminal 12 that makes is in charged or electriferous state not; And control subordinate power consumption equipment, the power line of subordinate's controlled device is introduced through load wiring end 9, is connected to load wiring terminal 12.
During equipment work; Left lock shaft 3 is moved to the left 20 millimeters, right lock shaft 5 moves right 20 millimeters, get into respectively in left front door 2, the right front door 8 door closure obturator hernias, send electric hand handle 4 to clockwise rotate 90 °; Rotation axis 17, power transmission device 18 send electric position, and electric control unit is charged.The power factor of reactive power compensation unit 15 monitoring electrical networks, through the computer system above it, the real-time operation electrical network parameter; Decision drops into the capacity with the excision compensation condenser; Keep power factor of electric network between 0.92～0.95, effectively utilize electric energy, reduce waste of electric energy; The operational factor of vacuum feed switch ECU 10 monitoring electrical networks is when electrical network breaks down, for example: short circuit, overload, in time trip protection load equipment and electrical network during uneven, electric leakage mutually.
When quitting work, move right 20 millimeters, right lock shaft 5 of left lock shaft 3 are moved to the left 20 millimeters, get into respectively and send in electric hand handle 4 lockholes, send electric hand handle 4 to rotate counterclockwise 90 °, rotation axis 17, power transmission device 18 power failure positions, electric control unit is not charged.
