Abstract
The utility model discloses an explosion -proof control box in electric scene based on optical cable transmission, the explosion -proof control box in electric scene is the explosion -proof box of polyester fiber, the one end that lies in the box on the heat transfer plate of the explosion -proof control box in electric scene outside has a plurality of comb -shaped heating panels of lining up, lies in the inside one end connection first pass heat conductor of box on the heat transfer plate, CPU control module on the circuit board in the explosion -proof control box in electric scene connects the heat transfer conductor, still be equipped with photoelectricity data conversion module on the circuit board, this photoelectricity data conversion module is connected CPU control module.
Description
Technical field
The utility model belongs to technical field of electric equipment, particularly a kind of electric on-the-spot explosion-proof control box based on optical cable transmission.
Background technology
Electric field control case Main Function is the control box of the other operating equipment start and stop nearby of equipment at the scene, existing application be all adopt electric signal control, by the adhesive of button, send electric signal order, make to do corresponding action after the contactor of switchgear building obtains signal, to reach the object of opertaing device.This structure is comparatively simple, but the situation that the order being only applicable to Long Distant Transmit is little.Control box will obtain the simulating signals such as current/voltage at the scene, separately must install digital display meter display additional.If because long distance transmits, make simulating signal decay or drag for by dry, data generation deviation can be made.Meanwhile, if when needing to transmit a large amount of control signal, cost can become very high.
Adopt the field control case of optical cable transmission, be change light signal dress into electric signal, control for button indicating lamp; Again 4 ~ 20mA current signal is converted to light signal simultaneously and deliver to operation room for monitoring.In opto-electronic conversion, modulator-demodular unit and working power can produce certain heat, however in explosion-proof area field control case again cannot with extraneous UNICOM, dispel the heat.Under extreme weather conditions, the temperature inside the box is too high, can affect the normal work of electronic component, and affect its mission life.Therefore, explosion-proof control box must be adopted at explosion-proof area.
Utility model content
The utility model provides a kind of electric on-the-spot explosion-proof control box based on optical cable transmission.
The technical solution of the utility model is, a kind of electric on-the-spot explosion-proof control box based on optical cable transmission, and described electric on-the-spot explosion-proof control box is dacron anti-explosion box body,
The one end heat transfer plate of described electric on-the-spot explosion-proof control box being positioned at casing outside has multiple heat sink lining up comb Like, and one end heat transfer plate being positioned at box house connects a heat conductor,
CPU control module on wiring board in described electric on-the-spot explosion-proof control box connects described heat conductor,
Described wiring board is also provided with photooptical data modular converter, and this photooptical data modular converter connects described CPU control module.
The utility model efficiently solves at the climate control issues of explosion-proof area use based on the electric field control case of optical cable transmission.

Embodiment
As shown in Figure 1, electric on-the-spot explosion-proof control box based on optical cable transmission of the present utility model, described electric on-the-spot explosion-proof control box is dacron anti-explosion box body, the one end heat transfer plate of described electric on-the-spot explosion-proof control box being positioned at casing outside has multiple heat sink lining up comb Like, one end heat transfer plate being positioned at box house connects a heat conductor, CPU control module on wiring board in described electric on-the-spot explosion-proof control box connects described heat conductor, described wiring board is also provided with photooptical data modular converter, this photooptical data modular converter connects described CPU control module.
Explosion-proof control box of the present utility model passes through heat conductor, the heat produced when being worked by CPU, is sent to heat transfer plate, then to be sent to by heat on the heat sink outside anti-explosion box body by heat transfer plate, can effectively reduce CPU working temperature like this, prevent the too high normal work affecting operation circuit of temperature.
