Referring to fig. 2, when the refrigeration compressor starts to operate, the movable contact 4 and the fixed contact 5 of the protector are in contact, the operating circuit of the refrigeration compressor is in a closed state, current flows through the heating element 2 of the protector, the temperature of the heating element 2 rises, and the heating element 2 diffuses heat to the periphery, so that the temperature of the protector rises, and the temperature of the bimetal 3 also gradually rises. As shown in fig. 3 and 4, when the bimetal 3 of the protector is increased in temperature, it is gradually deformed by heat. When the temperature of the bimetallic strip 3 reaches or exceeds the set operating temperature T0When the double metal sheets 3 are deformed and turned over, the movable contact 4 is driven to be separated from the fixed contact 5, and a circuit is disconnected, so that the refrigeration compressor and the refrigeration appliance are protected. Due to the physical properties of the bimetal 3 itself, when the bimetal 3 drops to its set recovery temperature T1In the following, it will be heavyThe new upset resumes, bringing the moving contact 4 back into contact with the stationary contact 5, thus completing the circuit again. Therefore, the protector with the bimetallic strip structure is a protector with an automatic recovery function, and has the characteristics of simple structure, low cost and the like. However, under certain extreme conditions, such as an electrical short circuit or a fault of the protector itself, the temperature of the protector rises sharply, and the movable contact 4 and the fixed contact 5 of the protector are still in a closed state, so that the circuit cannot be completely disconnected in time, and the conditions of compressor fault, ignition, combustion and the like can be caused.

The utility model aims to solve the technical problem that a take support the protector structure of adjusting the pole for the compressor of disconnected circuit in time, permanently when specific situations such as electric short circuit, protector self trouble take place is proposed.
In order to solve the technical problem, the utility model relates to a protector structure of regulation pole is supported with area includes casing, heating element, bimetallic strip, movable contact, stationary contact, support and adjusts pole and fuse, the movable contact is fixed on the bimetallic strip, the bimetallic strip is fixed on supporting the regulation pole, it installs to support the regulation pole on the casing, stationary contact fixed connection in on the casing with the corresponding position department of movable contact, heating element locates in the casing, the fuse is established ties in working circuit, the fuse is set for one fusing temperature TdThe bimetal is set with an operating temperature T0And a recovery temperature T1Said fusing temperature TdGreater than the operating temperature T0。
The fusing temperature T of the protector structure with the support adjusting rod for the refrigeration compressordThe temperature range of (A) is 150-800 ℃.
The above protector structure with the support adjusting rod for the refrigeration compressor is provided with one or more heating elements.
The above protector structure with the support adjusting rod for the refrigeration compressor is provided with one or more bimetallic strips.
The above-mentioned protector structure of adjusting pole is supported with area to refrigeration compressor, the fuse is equipped with one or more.
The utility model discloses owing to adopted above-mentioned technical scheme, when taking place the extreme condition such as electric short circuit or protector self breaks down, and when leading to the inside temperature of protector to rise sharply, even make the movable contact and the stationary contact of protector still be in the closed condition, nevertheless owing to establish ties the fuse in the working circuit, the fuse reaches the fusing temperature T of settlement because of the temperaturedAnd the circuit is permanently disconnected by timely fusing, thereby effectively avoiding the occurrence of accidents such as compressor failure, fire burning and the like and achieving the purpose of safety protection.
