Problems solved by technology

[0003] 10kv switchgear is widely used in the power industry. It has good switching effect and insulation effect, and has good safety and ease of operation. However, there are also many problems in the existing 10kv switchgear. Among them, the most problematic Obviously, the cleaning problem in the cabinet, the existing 10kv switchgear must be stopped for cleaning, which will affect the normal production, and at the same time, the opening and closing of the 10kv switchgear due to the cleaning work will affect the service life of its circuit breaker , reducing the safety of the switchgear. In addition, if the cabinet is not cleaned in time, it may affect the insulation of the switchgear and endanger the safety of people or equipment.

specific Embodiment 1

[0041] Such as figure 1 , a 10kv switchgear for purification and dust removal of the present invention includes a cabinet body, and a dust removal mechanism is provided on the cabinet body. The dust removal mechanism includes a gas storage tank 1, a purification mechanism 3, a decompression mechanism 2, a booster mechanism 5, and a heat exchanger 6. The air injection mechanism 7, the exhaust mechanism 4, the gas storage tank 1 is connected to the air injection mechanism 7 in the cabinet through the heat exchanger 6 and the decompression mechanism 2 in turn, and the cabinet is provided with an exhaust mechanism 4 to exhaust the air. The mechanism 4 is connected back to the gas storage tank 1 through the purification mechanism 3, the heat exchanger 6, and the pressurization mechanism 5 in turn, and the gas storage tank 1 is filled with inert gas.

[0042] The purification mechanism 3 includes a vacuum cleaner, a humidity controller, and an electroparticle adsorber connected in s...

specific Embodiment 2

[0049] According to the control system of the switchgear of embodiment 1, comprise:

[0050] (1), control unit;

[0051] (2) The purification unit includes a vacuum cleaner, a humidity controller, and an electric particle adsorber. The dust suction net in the vacuum cleaner filters the airflow; the filtered airflow enters the humidity controller, and the humidity controller includes a sponge net and an extruded plate. The sponge net has a number of curved through holes with a diameter not greater than 3cm and a length greater than 10cm. Activated carbon with a particle size of less than 5 mesh is arranged on the inner wall of the through hole. The sponge net absorbs the moisture in the airflow and filters the airflow again; Embosses are arranged horizontally on the pressing plate, the height of the embossing is 3-5mm, and the spacing of the embossing is 5-8mm. The extruding plate is connected with an extruder, and the extruder controls the extruding plate to extrude the sponge...

specific Embodiment 3

[0059] Purification method according to the control system of embodiment 2:

[0060] (1) After the airflow with cabinet dust enters the purification unit through the exhaust unit, it first enters the inlet of the vacuum cleaner. After the pleated dust net in the vacuum cleaner absorbs and filters the visible dust in the airflow, the airflow passes through the vacuum cleaner. The outlet is output, and the airflow is filtered for the first time on the vacuum net;

[0061] (2) The airflow output from the outlet of the vacuum cleaner enters the humidity controller, and the airflow is shunted in the humidity controller. The shunted airflow passes through the through holes on the sponge net respectively, and the moisture in the airflow is absorbed by the sponge. Or part of the particles are adsorbed by the activated carbon in the through hole, the airflow is filtered for the second time, and the airflow is collected at the outlet of the humidity controller and then enters the electr...

Abstract

The invention relates to a 10 kv switch cabinet realizing purifying and dedusting. The switch cabinet comprises a cabinet body. The switch cabinet is characterized in that the cabinet body is provided with a dedusting mechanism. The switch cabinet is simple in structure, convenient to use, convenient to popularize, applicable to all cabinet inner cavity structures of various kinds of switch cabinets and good in dedusting effect. According to a purifying method, a heating current is matched with an air extraction speed, an optimal purifying effect is achieved, so that the service lifetime is prevented from being influenced by a large temperature difference, which is caused by insufficient air preheating, between purifying air and a cable; a stage-type air feed mode is adopted to avoid impacts on a dedusting device, a preset 1.8 kpa air pressure is finally achieved, the best work is realized, and the best purifying effect is realized; in addition, a magnetic field between electric field plates is just adapted to the absorption of charged particles thereof, so that the charged particles are effectively prevented from entering the switch cabinet, and the reduction of the safety of the switch cabinet is avoided.

Description
