Abstract
The utility model discloses a mine used flame-proof type medium voltage frequency conversion speed-regulating device, which is composed of a flame-proof box, a line inlet box and a line outlet box, wherein a flame-proof line inlet and outlet plate is arranged in one side of the flame-proof box, a baffle plate is integrally formed in the middle of the line inlet box and a line outlet box, the baffle plate divides the flame-proof line inlet and outlet plate into an upper part of the line inlet box and a lower part of line outlet box, the outer wall of the line inlet box is provided with a power cord leading inlet and a control line inlet, and a load line leading outlet and a control line leading outlet are arranged on the side wall of the line outlet box. The mine used flame-proof type medium voltage frequency conversion speed-regulating device is adopted, since the line inlet box and the line outlet box are arranged on one side of the flame-proof box, the line inlet box and the line outlet box are integrally separated in the middle, line inlet and outlet are convenient, and inner line arrangement is convenient.
Description
Technical field
The utility model belongs to a kind of flame-proof mine device, particularly a kind of flame-proof mine medium voltage converter speed regulating device.
Background technology
Previous flame-proof mine medium voltage frequency converter kind equipment junction box has adopted two kinds of arrangement forms, promptly is being provided with respectively above the explosion-proof chamber or about inlet wire case, wire box.Junction box's form is arranged in the top, has increased whole height, is not easy to the down-hole and installs and uses.The structure that is provided with respectively about inlet wire case, wire box has increased entire length, and advances wire box and be distributed in both sides, makes the wiring inconvenience.Circumstance complication under the coal mine, the space is restricted, and equipment is too high or long all is inconvenient to use.
Summary of the invention
It is short that the purpose of this utility model provides a kind of entire length, and volume is little, and the turnover line is flame-proof mine medium voltage converter speed regulating device easily.
For achieving the above object, solution of the present utility model is: a kind of flame-proof mine medium voltage converter speed regulating device, form by Flameproof box, inlet wire case, wire box, be provided with flame proof in one side of described Flameproof box and advance outlet board, described flame proof advances the dividing plate that is formed with of the middle one of outlet board, described dividing plate advances outlet board with flame proof and is divided into inlet wire case and wire box two parts up and down, the outer wall of described inlet wire case is provided with power line intake and control line inlet port, and described wire box sidewall is provided with load line outlet and control line outlet.
Adopt above-mentioned flame-proof mine medium voltage converter speed regulating device because inlet wire case and wire box are arranged on Flameproof box one side, inlet wire case and wire box be one intermediate section every, the turnover line is made things convenient for, inner winding displacement is simple and direct.Power line mouth and control line connection jaws are arranged in the junction box front side, and the wiring case lid has reduced the explosion-proof chamber total length in the junction box left side, also makes wiring convenient.To advance wire box and be arranged on explosion-proof chamber left side, inlet wire case and wire box be one intermediate section every, can under the charged situation of inlet wire case, behind the disjunction isolating switch, operate wire box.
