Background technology
Explosion-proof malleation cabinet be applied to chemical industry, offshore drilling platform, metallurgy, medicine, light industry, weaving, food, bioengineering,
In the explosive gas such as space flight and aviation engineering and military project or dust atmosphere, to three-phase four-wire system (380v/220v) AC low-tension
Electrical equipment distribution system is powered or to elements such as instrumentation, analysis meter, monitor, micro computer touch-screen, big-power transducers
It is monitored and control.
Explosion-proof principle: isolate the explosion precaution of ignition source using medium.That is: the electric elements used by user are arranged on one
In the individual cabinet full of malleation clean gas, make inflammable and explosive mixed gases in external environment condition cannot touch electric elements
Produced electric spark or dangerous temperature in normal work, thus reach the explosion-proof purpose of electrical equipment.
At present conventional explosion-proof positive pressure cabinet controller in industry is with traditional time relay, auxiliary reclay, omnipotent
Control process realized by these single elements such as digital displaying meter by control circuit, and Circuit assembly process takies manpower comparing relatively
Many, and because assembler professional standards are different, assembling quality is also impacted, and generally speaking, volume ratio is larger, artificial and direct material
Material cost is higher.
Utility model content
The utility model proposes a kind of automatic controller of explosion-proof malleation cabinet, solve controller in prior art electric
Component size is big, wiring assembling when man-made assembly, high cost, quality is also unstable, material cost is higher problem.
The technical solution of the utility model is achieved in that a kind of automatic controller of explosion-proof malleation cabinet, including shell
Body and rear end cap, housing and rear end cap connect and seal, and housing front is provided with form and button, and case inside is provided with interior ground connection and connects
Head, housing lower end has turnover cable port, and rear end cap is provided with support, and support is connected with circuit board, circuit board and liquid crystal display
Screen connects, and LCDs is alignd with viewing window position.Sealed by sealing ring between housing and rear end cap.Interior ground joint includes
Interior earthing screw and interior ground connection screw.Button includes key body and spring, key body and spring cooperation.It is provided with turnover cable port
