Abstract
The utility model belongs to the field of pneumatic operating mechanisms in electrical devices and specifically relates to a high-voltage electrical switch pneumatic operating apparatus. A technical scheme employed by the utility model is that the high-voltage electrical switch pneumatic operating apparatus comprises an electromotor, an air compressor, and a cylinder, that an air filtering device is installed on a mother pipe between the air compressor and the cylinder, that a heating device is installed in the cylinder, and that the air filtering device comprises a cooling cabin and an air filtering core installed in the cooling cabin. The high-voltage electrical switch pneumatic operating apparatus has beneficial effects that the air filtering core in the cooling cabin removes redundant moisture and impurities in the compressed air required by an electrical device under low temperature so that required compressed air is continually supplied for the pneumatic operating mechanism in order to guarantee the operative reliability of the electrical device, and that the high-voltage electrical switch pneumatic operating apparatus effectively eliminates phenomena of water accumulation and frozen water of the compressed air stored in the pipe caused by external influence such as pressure and temperature, saves manpower, material resources, and repairing and maintaining time, and decreases loss to be within a minimum range.
Description
Technical field
The utility model belongs to pneumatic operator field in electric equipment, specifically a kind of high-voltage electrical apparatus switch pneumatic operation device.
Background technology
Present widely used SF 6 high-voltage electric switch in electric power system; realized effective interlock protection; and former thereby obtain user's favor because floor space is little, maintenance cycle is long, coefficient of safety is high etc.; its pneumatic operating system relies on the compressed air gas pressure to complete disconnection and the closure of its switch; in case and pneumatic operating system breaks down; will cause control loop to break; automatically cutting-off controlling loop and can not normally carry out deciliter, so the whether normal direct relation of pneumatic operating system the normal operation of electric equipment and electrical system.
Compressed air is stored in an airtight cylinder in long-term use procedure, because being subjected to the impact of temperature, pressure, gas very easily produces moisture, and the moisture of the prolonged stay continuous corrosion pipeline of meeting and electric equipment, cause electric equipment normally not move, when temperature is too low especially in the winter time, because causing to have a power failure, the phenomenons such as pipeline freezes, pipeline breaking process, extract certain manpower, time out and carry out blowtorch heating and maintenance work, not only affect normal production but also cause unnecessary labour's waste.Therefore, ensure that the pneumatic operator of electric equipment has good drainage arrangement, avoid occurring ponding, icing phenomenon, to ensure the safe operation of electric equipment.
Summary of the invention
Technical problem to be solved in the utility model is: the moisture and the impurity that how just in the electric equipment pneumatic operator, produce effectively filter out, and avoid simultaneously because temperature reduces the icing phenomenon of the pipeline that causes.
The technical scheme that the utility model adopts is: a kind of high-voltage electrical apparatus switch pneumatic operation device, comprise motor, air compressor, cylinder, on the female pipe between described air compressor and described cylinder, air filter is installed, in described cylinder, heater is installed, described air filter comprises cold storehouse and is arranged on the air filtration core in cold storehouse.
The beneficial effects of the utility model are: the utility model makes the required compressed air of electric equipment remove unnecessary moisture and impurity by the air filtration core in cold storehouse at low temperatures, supply with continuously the required compressed air of pneumatic operator, ensure the reliable rate of electric equipment.Effectively stopped simultaneously to be stored in compressed air in pipeline owing to being under pressure, the ectocine such as the temperature ponding, the phenomenon of freezing that cause, save human and material resources and inspection and maintenance time, loss is reduced within minimum scope.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
as shown in Figure 1, in original pneumatic operator, the female pipe that connects between air compressor and cylinder is taken apart, the middle above air filter that connects, air filter is a cold storehouse and is arranged on the air filtration core in cold storehouse, by this air filter can effective filtration pressure contracting air in unnecessary moisture and impurity, heater such as electric furnace heating wire etc. are installed simultaneously in cylinder, when temperature is very low, suitably heat, thereby avoid airborne condensate moisture, the compressed air that keeps simultaneously proper temperature, avoid when temperature is too low in the winter time causing electric equipment not use.During use, motor band engine-driven air compressor work, at first air enters Leng Cang after compressed air is compressed, and after in cold storehouse, carrying out air filtration, then enters cylinder and stores, and the pneumatic operator of supply arrangement uses.When electric equipment need pneumatic operator to release energy to promote circuit breaker deciliter the time, the compressed air that stores in cylinder is utilized release, thereby cause junction closure, re-starts the compressed-air actuated of a new round and suppresses transmission and store.
The key point of the technical program is before the pneumatic operating mechanism use compressed air of electric equipment, to it, to carry out moisture and contaminant filter, guaranteed the aridity of air, prevent that moisture from entering the compressed-air actuated pipeline of conveying and device, ensured the stable operation of electric equipment, prevent that simultaneously electric equipment from causing the appearance of contingency because of moisture, reduce human and material resources and temporal investment, greatly shorten the abnormal operation of electric power system time, thus the safe operation of effective guarantee electrical network.
