Abstract
The utility model discloses a mineral explosion suppression composite feeding switch, which includes a support, an explosion suppression tank, a door, and a binding post, a breaker and a protector; wherein the display screen of the switch and a control button are arranged on the door, which are characterized in that the explosion suppression tank is provided with a bracket, wherein the bracket is provided with at least two drawers; and each drawer is provided with an insulating plate that is provided with the breaker, protector and the binding post; and each drawer is formed a feeding switch, wherein one of the feeding switch is the master switch. The utility model combines the master switch with the branch switch into a whole, which can reduce the land occupancy of the feeding switch and save substantive explosion suppression tanks, thus reducing the service cost of the feeding switch to a large extent and the complex binding of the initial switch and the branch switch as well, so as to make the service and maintenance of the feeding switch more safer and convenient.
Description
Technical field:
The utility model relates to a kind of contactor, particularly a kind of explosion-proof feeding switch that is used under the mine.
Background technology:
Present widely-used explosion-proof feeding switch under the mine, what be used for underground power supply system send electricity or outage.This switch comprises base, Flameproof box, door, lead-in clamp, output wiring terminal and circuit breaker, protector; circuit breaker and protector are packed in the Flameproof box by insulation board, and the display panel of protector and control button are arranged on door and go up so that Direct observation and operation.Present this switch generally is to be divided into secondary to use, promptly be divided into the master switch supporting use that links to each other with switch-dividing, power line inserts the lead-in clamp of master switch, and the output wiring terminal of master switch and the lead-in clamp of switch-dividing are electrically connected, and the output wiring terminal of switch-dividing and load are electrically connected; General and a plurality of switch-dividings of master switch are electrically connected.This monomer-type switch in use has the defective that floor space is big, use and keep in repair inconvenience.
Summary of the invention:
The purpose of this utility model is the flame-proof mine composite type feeding switch that floor space was little, use is easy to maintenance during a kind of total feeding switch of design and branch feeding switch were combined into one, use.
The realization the technical solution of the utility model is, a kind of flame-proof mine composite type feeding switch, comprise base, Flameproof box, door, lead-in clamp, output wiring terminal and circuit breaker, protector, the display screen of protector and control button are arranged on the door, it is characterized in that, be provided with support in the Flameproof box, at least two drawers are set on the support, insulation board is all arranged in each drawer, circuit breaker is arranged on the insulation board, protector and lead-in clamp, output wiring terminal, each drawer constitutes a feeding switch, and one of them feeding switch is total feeding switch, and its capacity is bigger; Remaining is for dividing feeding switch, and the output wiring terminal of total feeding switch and the lead-in clamp of other switch are electrically connected.
After the utility model is combined into one master switch and switch-dividing, can effectively reduce the floor space of feeding switch, save that a large amount of accuracies of manufacture is had relatively high expectations and heavy Flameproof box, thereby reduce the use cost of feeding switch significantly, simultaneously, reduce the wiring complexity of master switch and switch-dividing, make the safe ready more of the use maintenance change of feeding switch.
Description of drawings:
Fig. 1 is a structural representation of the present utility model, and wherein the door imagination is removed, and does not draw in the drawings.
Fig. 2 is the structural representation that drawer of the present utility model amplifies.
Number in the figure: 10 bases, 20 supports, 21 base plates, 22 vertical rods, 23 cross bars, 30 drawers, 31 pins, 32 total feeding switchs, 40 trip bolts, 50 Flameproof boxes, 60 insulation boards.
Referring to accompanying drawing 1, support 20 becomes at least two drawer chambers with the separated by spaces in the Flameproof box 50, have two drawers 30 in the Flameproof box 50 at least, be provided with insulation board 60 in each drawer 30, components and parts such as circuit breaker, protector are installed in (components and parts such as circuit breaker, protector do not omit and draw) on the insulation board 60, also be provided with the input and output binding post on the insulation board 60, each drawer 30 has all constituted an independently feeding switch; In the above-mentioned drawer 30 one, components and parts such as the circuit breaker on its insulation board 50, protector are by total feeding switch configuration, this drawer 30 constitutes total feeding switch 32, and components and parts such as the circuit breaker in other drawer 30, protector are pressed the switch-dividing configuration, and these drawers constitute the branch feeding switch; Electric power incoming line links to each other with the lead-in clamp of total feeding switch 32, its output wiring terminal respectively with other minute feeding switch lead-in clamp be electrically connected, these minutes feeding switch output wiring terminal and load electrical connection; Support 20 is made of base plate 21, cross bar 23 and vertical rod 22, and support 20 is fastened in the Flameproof box by base plate 21 by trip bolt 40, and drawer 30 is arranged on the cross bar 23, when drawer 30 is not fastening, can extract out in support 20 easily or push; Referring to accompanying drawing 2, drawer 30 is provided with the pin 31 of guiding and location, and the pin-and-hole that matches with pin 31 is arranged on the cross bar 23, after drawer 30 pushes, in the pin-and-hole that pin 31 is sold on the cross bar 23 and by bolt drawer 30 and support 20 is tightened together.The display screen of the protector of above-mentioned total feeding switch and branch feeding switch is arranged on the door, can a display screen be set each switch, also a display screen can only be set, and shows the wherein information of any one switch as required by control button.
