Features

1. Adopts medium separate ignitor to achieve the explosion-proof aim. That is putting all the explosion-proof components in the shell filled with positive pressure clean medium, the medium can stopping electric ignitor or hazardous high temperature reaching electric components, to achieve explosion-proof aim.

2. The products can be fixed with inspection meter, analysis meter, vision meter, monitor, micro-computer touch screen, high power transducer and other electric components, the inside components are unlimited.

3. Adopts main switchboard, and auxiliary switchboard structure, main switchboard is the pressurised chamber, inside installed the components and the needed sense system,ventilating system and pressure adjustment system. Inside auxiliary switch board self-control explosion-proof pressure displaying, in and out gas sources connection entry. The self-supply gas type also have explosion-proof gas supplying system.

4. There are box style, musical plate style and board style, the board are divided into fluctuated into right and left structure, the body is welded by steel plated and sprayed with plastic, the board shelf is welded by standard profiled bar, surface is sprayed with plastic, the join plate is handle sealing, treatment operating from frontal door and maintaining from back door. Normally we select GB710-88 cold castled steel, also can select GB280-84 stainless.

Noted:If you have special requirements for erosion-proof class,Indicate it when ordering.Function InstructionPX type pressurized distribution panel.1. With gas changing interlock.Before running,the main switchboard inner chamber changing gas,when the gas changing volume is ok,to assure the main switchboard below away the flammable explosive atmosphere,then the auxiliary can be power on to assure the secure running.2. Only when inner pressure of main switchboard meet request,the power conversion system can supply power to the main switchboard.3. Working pressure in main switchboard chamber is 80Pa<P<500Pa.When pressure is reach 500Pa,the self-control system will close air-intake valve or discharge valve to avoid the distortion of high pressure impact.When pressure is less than 80Pa,self-control system alarms automatically (acoustic and lighting),open air-intake valve to add gas into switchboard.When the pressure reduce to 50Pa,the system can be set to break automatically in case of nesesity.4. Auxiliary self-control system in continuous monitor and display pressure parameters of main switchboard.5. When ambiance is confirmed in a safe condition,”by pass” can be used,which can ensure the main power does not necessary to shut down as the main door opens(the difference between inside pressure and outside is zero).in order to test circuits in the box.6. Pressure ventilating type is continuous wind sending,working the rmal of pressure chamber can be dispatched in time to assure the dispatching thermal.Inside install meter displaying meter,soft starter,computer etc.The integral device can be used as machine start,signal management and control system.7. Same type products can be combined running.8. When user providing gas source,the gas should clean and of inactive gas.Normally,the service meter can meet request,gas pressure is 0.35MPa≦P≦0.66MPa.9. The product can be used in power system of three-phase four-wire 380/220 system and all weak electricity system,can not be used in high-voltage system. PZ type pressurized distribution panel Specially design for zone 2 areas.PZ compare to PX type,it omits the overhauling time’s safe clearance.Only marking gas changing time,changing gas on request before the master energize by user.When inner pressure is less than 80Pa,self-control system alarms automatically(acoustic and lighting),open air-intake valve to add gas into the switchboard.When adding finished,the system recovers.if failed,when the pressure reduce to 50Pa,the power will not be off automatically,and go on to alarm. Outline of box style
