Abstract
The utility model relates to a mining electrical control chest, which comprises a main cavity and a wiring cavity in a chest body. A power module, a PLC module, and an isolating paling module are arranged in the main cavity body, wherein, the PLC module comprises 48 input switching value signals, 8 analogue value signals, and 16 out switch quantity signals. The mining electrical control chest cancarry out the conversion of the flame-proof and none flame-proof by adopting the isolating paling structure, can remotely operate and control the electrical device by adopting the PLC control device,and has the advantages of simple operation, stable reliable property, and convenient maintenance.
Description
Technical field
The utility model relates to a kind of mining electric cabinet.
Background technology
Electric cabinet has been widely used in the mine, has played protection and control action for the various electrical equipments under the mine.The electric cabinet major part of using in the mine can produce a large amount of heats when work at present, and is not easy to the signal of the various electrical equipment feedbacks in the mine is handled, and can not carry out the conversion of mine flame proof and non-flame proof simultaneously.
Summary of the invention
The purpose of this utility model is to improve above-mentioned deficiency of the prior art and a kind of mining electric cabinet is provided, and has solved the conversion of mine flame proof and non-flame proof, simultaneously can control and protects various electrical equipments in the mine.
The purpose of this utility model reaches by following measure:
A kind of mining electric cabinet comprises main chamber and wire connection cavity in the casing, is provided with power module, PLC module, isolated gate module, flameproof joint in the main cavity.Described PLC module is electrically connected with the isolated gate module.
Wherein the PLC module comprises 48 input switch amount signals, 8 analog signalses, 16 output switching value signals.
The housing outer wall of described casing scribbles anticorrosive coat, and the inner walls of described casing scribbles arc-resistant enamel paint.
Advantage of the present utility model is:
The utility model is mining, and electric cabinet adopts the isolated gate structure can carry out the conversion of flame proof and non-flame proof, has adopted the PLC opertaing device to carry out operated from a distance and control to electrical equipment simultaneously.
Description of drawings
Fig. 1 is mining electric cabinet inner structure synoptic diagram;
Fig. 2 is mining electric cabinet front view.
Embodiment
As illustrated in fig. 1 and 2, a kind of mining electric cabinet comprises main chamber and wire connection cavity in the casing, is provided with power module 1, PLC module 2, isolated gate module 3, flameproof joint 4 in the main cavity.Wherein PLC module 2 comprises 48 input switch amount signals, 8 analog signalses, 16 output switching value signals.Be provided with 7 tunnel isolated gates on ground altogether not in the electric cabinet, as the conversion of flame proof and non-flame proof.The signal of the on-the-spot various sensors of mine is gathered in the input of switching value and analog quantity by PLC, and when electrical equipment broke down in the mine, electric cabinet was handled the signal of electrical equipment feedback, disconnects all external equipments.Insulation resistance in the electric cabinet between energized circuit and the ground should be no less than 20M Ω.
During work; feed the 127V AC power to electric cabinet, when frequency converter breaks down or during sealing-tape machine generation coal piling fault, frequency converter or coal piling defence program switch feed back a normally closed signal to electric cabinet; handle through electric cabinet, disconnect the electrical equipment that to protect other after all output signals.The operator's console of electric cabinet is provided with " manually " shelves and " automatically " grade, presses each startup, stop button respectively, can realize the work of each equipment or stops.The electric cabinet surface also is provided with display screen, the duty of corresponding external equipment, and under the normal operating conditions, the status indicator lamp of external equipment is green, when device fails or when stopping, corresponding pilot lamp becomes redness.The housing outer wall of electric cabinet casing scribbles anticorrosive coat, and the inner walls of casing scribbles arc-resistant enamel paint.
The utility model can be operated under-10 ℃ to+40 ℃ environment, sealing-tape machine electric control system in the mine of can be used for that explosive mixture is arranged (for example methane mixture) and coal dust.The utility model electric cabinet is simple to operate, stable and reliable for performance, maintains easily.
