Abstract
The utility model relates to a control cabinet of explosion proof electrical appliance for guaranteeing the safety application of the oil-fired boiler and the gas-fired boiler, comprising a totally enclosed cabinet case made of an integral sealing treated plate with a power distribution unit of the boiler and a control unit of the instruments and electrical appliances, a resetting mechanism combined with the dynamic unit and the control unit is arranged on the side wall of the cabinet case, a distribution inlet, a distribution outlet and a condensate drain outlet. The utility model has the advantages that the control cabinet of the electrical appliance is with reasonable structure and beautiful appearance, can effectively avoid the discharge phenomenon led by electric arc spark and reach the explosion proof purpose for the controlling device of the boiler and the electrical appliances.
Description
Affiliated technical field
The utility model belongs to electrical equipment control facility technology field, boiler room, relates to a kind of explosion-proof electric apparatus control cubicle that ensures fuel oil, gas fired boiler safe handling.
Background technology
Boiler room electrical equipment control facility mainly comprises electric distribution unit (calling power unit in the following text) and electrical instrumentation control unit (calling control unit in the following text) two parts, and it is the key facility that ensures the high efficiency boiler safe operation.In recent years, along with the pay attention to day by day that country administers atmospheric environment, the original coal fired boiler in various places is just progressively replaced by fuel oil, gas fired boiler, and this has just proposed a new requirement for the electrical equipment control problem in the boiler room.Clearly stipulate to be class two zone in fuel oil, the gas fired boiler room in GB50058-95 number " State Standard of the People's Republic of China's code for design of electric installations within explosion and fire hazard atmospheres " of the promulgation in 1992 of China's fire department, the use of its indoor electric appliance need be used explosion-proof type.But owing to the domestic present fuel oil of China, gas fired boiler are in the starting developing stage, electrical control part substantially still prolongs the used type of using in the past of coal fired boiler, and this makes fuel oil, gas fired boiler room use the on-the-spot very big fire explosion hidden danger that exists undoubtedly.On the other hand, field with regard to explosion-proof electric apparatus production at present, power distributing cabinet and light distribution box major part that the domestic more existing special-purpose explosion-proof electric apparatus manufacturers of China produce are cellular construction, can't satisfy the requirement of boiler operatiopn and boiler control, and they exist also that cost is higher, assembling profile in unit is not attractive in appearance, can't observe, use defectives such as inconvenience and maintenance difficulty are big.
Summary of the invention
The purpose of this utility model is at the existing in prior technology defective, and a kind of rational in infrastructure, good looking appearance, easy to use, fuel oil, the gas fired boiler explosion-proof electric apparatus control cubicle that can fully satisfy boiler control apparatus safe operation requirement are provided.
The technical solution that adopts is so for achieving the above object: the fuel oil that is provided, gas fired boiler explosion-proof electric apparatus control cubicle have a totally-enclosed cabinet shell of being processed into by the sheet material integral sealing, in the cabinet shell, be packaged with power unit and control unit, on the cabinet shell side wall, be provided with and power unit and the control unit manual shift fork resetting device that telegraph key combines that resets, also be provided with distribution incoming line, line outlet and condensate drain outlet on the cabinet shell side wall, the body of all break-through cabinet shells all combines with the sealing of cabinet shell shell wall in the cabinet.
The utility model is by above-described improvement project, with the power unit of original boiler electrical equipment control facility and control unit be sealed in fully one with the isolated cabinet shell of extraneous air in, the arc spark electric discharge phenomena be can prevent effectively like this, fuel oil, the explosion-proof purpose of gas fired boiler electrical equipment control facility reached.
Description of drawings
Fig. 1 is the structural representation of a specific embodiment of the utility model.
Embodiment
As shown in the figure, fuel oil described in the utility model, gas fired boiler explosion-proof electric apparatus control cubicle comprise that one has the totally-enclosed explosion-proof type cabinet shell 1 with perfect physique structure of hard plate material one welding, bonding or the casting of higher-strength with copper alloy, cast iron, cast steel, aluminium alloy, plastics etc., and the external shape of cabinet shell 1 can be multiple bodies such as square body, rectangular body, circle or oval casing.Boiler power unit 2 and control unit 3 all are located in the explosion-proof cabinet shell 1.On cabinet shell 1 sidewall, be provided with manual shift fork resetting device 4; resetting device 4 can be single shift fork resetting device or a plurality of shift fork resetting device; its fork and power unit 2 and control unit 3 telegraph key that resets combines, and can realize resetting of electrical equipment in the cabinet by resetting device 4 during work and protects.On the front panel of cabinet shell 1, be provided with the transparent instrument form that welds or bond and form by a plurality of transparent plastics or glass, can see all situations and the numerical value that boiler carries out intuitively by these transparent instrument window-operating persons, and then detect the operation conditions (comprising detection) of boiler operating index such as boiler hearth temperature, leaving water temperature, return water temperature, steam flow and temperature, pressure, flue-gas temperatures; Cabinet control button 8 also all is located on the front panel of cabinet shell 1.On cabinet shell 1 sidewall, also be provided with distribution incoming line 5, line outlet 6 and condensate drain outlet 7 etc., require all these bodys all must combine on the cabinet processing technology with the sealing of cabinet shell 1 shell wall.Sequence number 9 is an indicator light among the figure.
Fuel oil described in the utility model, gas fired boiler explosion-proof electric apparatus control cubicle have plurality of advantages such as rational in infrastructure, that cost is low, property easy to use, safe is good, it is good looking appearance not only, inner electric elements are also very convenient when forming, chain, interlocking control when its inside function can fully satisfy the operation of fuel oil, gas fired boiler, superpressure, overtemperature, low water controlling alarm, automatic water supplement and blowing out many-sided functional requirement such as adjustings automatically, the use popularization of its product has high social effect and economic worth.
Claims (2)
1, a kind of fuel oil, gas fired boiler explosion-proof electric apparatus control cubicle, it is characterized in that having a totally-enclosed cabinet shell (1) of being processed into by the sheet material integral sealing, in cabinet shell (1), be packaged with electric distribution unit (2) and electrical instrumentation control unit (3), on cabinet shell (1) sidewall, be provided with and electric distribution unit (2) and instrument control unit (3) the manual shift fork resetting device (4) that telegraph key combines that resets, on cabinet shell (1) sidewall, also be provided with distribution incoming line (5), the body of all break-through cabinet shells (1) all combines with the sealing of cabinet shell (1) shell wall in line outlet (6) and the condensate drain outlet (7), cabinet.
