The explosion-proof high-voltage motor is provided with an explosion-proof shell, and the explosion-proof shell can separate an electric part which generates sparks, electric arcs and dangerous temperature from a surrounding explosive gas mixture. In order to meet the explosion-proof requirement, the explosion-proof shell is designed to be thicker, so that the weight of the explosion-proof high-voltage motor is far heavier than that of a common high-voltage motor with the same power in terms of weight alone, and the weight of a junction box of the explosion-proof high-voltage motor is also far heavier than that of the common high-voltage motor with the same power.

Generally, in order to ensure the safety of the device, the overhaul period of a device area of oil refining, chemical engineering and the like is one year, a half or two years, during the overhaul period, electrical workers can also emphatically inspect the high-voltage motor in the device area, wherein an important and necessary overhaul content is that a front cover of a power box of the explosion-proof high-voltage motor needs to be opened on site to inspect whether a connecting wire in the power box is loosened, whether water enters the power box to be damped or not and whether insulation is qualified or not, if water enters the explosion-proof high-voltage motor wiring box due to poor sealing and is damped, the insulation performance is affected or the connecting wire is loosened and has poor contact, electric arcs, short circuits and even explosions can be generated under a high-voltage environment, and the safety of the personnel and the device is seriously endangered.

Because the setting of most great powerful flame-proof type high voltage motor power supply box is heavier in casing one side and weight, can not only rely on the manpower to move during concrete operation, to the high voltage motor who sets up in the device district piping lane, the staff generally can be on the pipeline directly over the motor or steel framework to be affiliated to the back chain, hook the couple of back chain on the rings of motor power supply box protecgulum upside, dismantle the bolt between power supply box protecgulum and back lid and power supply box protecgulum and the bottom cable inlet wire mouth ring flange after having hung, then the pulling back chain, make power supply box protecgulum and back lid separation, the operating personnel overhauls inside according to the safety standard after the separation. Because the power box protecgulum is very heavy, hang and have the risk of dropping and pounding the staff on still having the pipeline of material, and to the motor that arranges in spacious position, this method can't use. Therefore, the staff can use the portal frame to hoist the power box protecgulum usually, during the use, need span the portal frame at the motor upside, because of the power box sets up in casing one side, can only draw the chain hoist to one side of portal frame crossbeam and use, the power box protecgulum can hang the one end at the portal frame crossbeam and lead to the portal frame atress inequality and beat and shake after hoisting, operation process needs many people to cooperate supplementary just can accomplish, and operation process has certain danger. After the motor power box is overhauled, the front cover of the power box can not be over against the rear cover during the repacking, the front cover and the rear cover can be well aligned only by the resultant force of a plurality of persons, and the repacking is completed.
