Background

The switch cabinet is an electrical device, the external line of the switch cabinet firstly enters a main control switch in the cabinet and then enters a branch control switch, and each branch is arranged according to the requirement. Such as meters, automatic control, magnetic switches of motors, various alternating current contactors, and the like, some are also provided with high-voltage chambers and low-voltage chamber switch cabinets, and high-voltage buses, such as power plants, and some are also provided with low-frequency load shedding for keeping main equipment. The main function of the switch cabinet is to open and close, control and protect electric equipment in the process of power generation, power transmission, power distribution and electric energy conversion of an electric power system. The components in the switch cabinet mainly comprise a circuit breaker, an isolating switch, a load switch, an operating mechanism, a mutual inductor, various protection devices and the like. The method is mainly suitable for various occasions such as power plants, transformer substations, petrochemical industry, metallurgical steel rolling, light industrial textile, industrial and mining enterprises, residential districts, high-rise buildings and the like. When the electrical cabinet works, each internal electrical component can generate heat to heat the cabinet body, and the cabinet body is overheated to cause the electrical component therein to break down, so that the power distribution is in a problem, and therefore, the protection measures such as heat dissipation and cooling are required to be carried out on the interior of the electrical cabinet.

In the application number: CN202110917023.9 patent document discloses an electrical cabinet with an electrical engineering fire-proof monitoring system, which includes a cabinet body, a partition plate, a cabinet air conditioner, a switch device, a vertical pipe, an air outlet groove and a temperature sensor; the partition plates are uniformly arranged in the vertical direction in the cabinet body, and each partition plate is fixedly connected with the inner surface of the side wall of the cabinet body; according to the invention, by arranging the partition plate, the air inlet groove, the trapezoidal lug and the vertical pipe, cooling air generated by the fan is discharged through the second air blowing port and the third air blowing port, so that heat dissipation and cooling are carried out on each surface of the switch equipment, and the heat dissipation efficiency is improved; by arranging the elastic sheet and the wire outlet, the vertical pipe can fix and contain a longer wire body or a loose wire body in the switch cabinet, the wire body is prevented from being wound and accumulated in the cabinet body to influence the flow of cooling air, and the heat dissipation efficiency is further improved; meanwhile, the use of other wire arrangement and wiring equipment is avoided, and the production energy consumption is reduced.

However, the following disadvantages still exist in the practical application process:

first, the heat dissipation effect to the regulator cubicle inside is poor, because the flow direction that above-mentioned comparison file fan produced the air current is even extensive inadequately, so lead to poor to the heat dissipation effect of regulator cubicle inside.

Second, during the heat dissipation, be convenient for carry out automatic clearance to the dust on filter screen surface, lead to artifical manual clearance filter screen comparatively to waste time and energy, because above-mentioned contrast file does not set up the mechanism that carries out the clearance to filter screen surface dust, so need artifical manual clearance.

Thirdly, inconvenient inside the regulator cubicle play a timely automatic fire extinguishing's effect, because above-mentioned file does not set up automatic fire extinguishing's mechanism, so need artifical handheld fire extinguisher to put out a fire, not only dangerous, can not in time put out a fire moreover.

Fourthly, when a fire disaster happens, an early warning effect is inconvenient to play, and because the comparison file is not provided with an early warning mechanism, personnel cannot timely know when the fire disaster happens.

when the heat dissipation work is carried out, the air circulation speed is accelerated, dust adheres to the surface of the filter screen 18, the second motor 31 drives the chain wheel 28 at the lower left end to rotate, the chain wheel 28 drives the chain 29 to rotate, the chain 29 drives the lifting plate 21 to move and slide on the sliding rod 19, meanwhile, the lower end of the sliding rod 19 slides left and right on the inner side of the sliding groove plate 20, the scraper 23 scrapes the dust on the surface of the filter screen 18 from top to bottom, when the scraper 23 is at the lowest end, the front end of the scraper 23 presses the extrusion block 34, the extrusion block 34 drives the second sliding column 36 to slide, the first spring 37 is extruded, meanwhile, the scraper 23 drives the first sliding column 22 and the third sliding column 47 to slide, the third spring 48 generates deformation, when the scraper 23 is not in contact with the extrusion block 34 any more, under the restoring action of the third spring 48, the scraper 23 vibrates, the dust on the surface of the scraper 23 is shaken off to the inside of the collection box 32, then the collection box 32 is drawn out, the dust can be poured out and cleaned, and accordingly, when the inside of the main body 1 is cooled, the dust on the left and right sides of the main body 1 can be cleaned, and the dust on the surface of the dust on the filter screen 18, and the dust can be cleaned manually, so that the dust can be automatically cleaned, and the dust on the filter screen 18, and the filter screen can be cleaned; when the smoke sensor 49 detects a fire, the second motor 31 does not work any more, the electromagnetic valve 38 and the first motor 4 are started simultaneously, the dry ice in the dry ice tank 39 reaches the inside of the spray pipe 13 through the hard pipe 9 and the hose 10 and is sprayed out through the through hole pipe 41, meanwhile, the first motor 4 drives the first connecting rod 5 to rotate, the first connecting rod 5 drives the first L-shaped rod 7 to slide up and down on the limiting rod 8 through the second connecting rod 6, when the first L-shaped rod 7 moves up and down, the rack 17 drives the gear 16 to rotate, the gear 16 drives the electrical cabinet 14 to rotate through the pin shaft, the second bevel gear 14 drives the spray pipe 13 to rotate through the first bevel gear 11, so that the through hole pipe 41 rotates up and down while reciprocating, and the dry ice is sprayed out widely and uniformly, therefore, when the fire is caught in the electrical cabinet main body 1, a timely, efficient and automatic fire extinguishing effect can be achieved on the inside of the electrical cabinet main body 1, and further the situation that people cannot extinguish the fire in time and labor manually and effort is avoided; first contact 52 and second contact 54 and circuit switch-on are nevertheless not circular telegram, when the conflagration takes place, hot melt 51 fuses, first contact plate 50 rotates under the effect of gravity, make first contact 52 and second contact 54 contact, make the circuit to the circular telegram of buzzer siren 56, can send out the police dispatch newspaper, remind personnel, only when the conflagration takes place, buzzer siren 56 just can be circular telegram and send out the police dispatch newspaper, when the conflagration does not take place, buzzer siren 56 is in the not electrified state, thereby not only realize the early warning effect, the loss of electric energy has also been saved.
