Description
Technical Field
The invention relates to the field of electrical equipment, in particular to a switch cabinet with a fire extinguishing function.
Background
The switch cabinet is an electrical device, the external line of the switch cabinet firstly enters the main control switch in the cabinet, then enters the sub-control switch, and each shunt is arranged according to the requirement. Such as meters, automatic control, motor magnetic switches, various ac contactors, etc., and high-voltage and low-voltage switchgear, high-voltage buses, such as power plants, etc., and low-cycle relief for protecting major equipment.
The main function of the switch cabinet is to open and close, control and protect electric equipment in the process of generating, transmitting, distributing and converting electric energy of the electric power system. The components in the switch cabinet mainly comprise a breaker, a disconnecting switch, a load switch, an operating mechanism, a transformer, various protection devices and the like. The switch cabinets are classified into a movable switch cabinet and a fixed switch cabinet according to the installation mode of the circuit breaker; or according to the different cabinet structures, the switch cabinet can be divided into an open switch cabinet, a metal closed switch cabinet and a metal closed armored switch cabinet; according to different voltage levels, the high-voltage switch cabinet, the medium-voltage switch cabinet, the low-voltage switch cabinet and the like can be further divided. The method is mainly suitable for various different occasions such as power plants, transformer substations, petrochemical industry, metallurgical steel rolling, light industry textile, factories and mining enterprises, residential communities, high-rise buildings and the like.
When the switch cabinet is normally used, partial heat can be generated in the switch cabinet, the temperature in the cabinet body needs to be timely reduced, meanwhile, the switch can often generate poor contact or short circuit at the positions of a wire inlet and a wire outlet, and therefore the switch is extremely easy to burn or the danger of fire disaster in the switch cabinet is extremely easy to cause.
Most of the existing switch cabinets do not have an automatic fire extinguishing function, some switch cabinets have a fire extinguishing function, but fire extinguishing agent nozzles of the existing switch cabinets with the fire extinguishing function are arranged on the outer side of a switch and are far away from an outlet and a wiring port of the switch, when a fire is caught in the wiring position of the switch, the fire extinguishing agent nozzles arranged on the outer side of the switch need a certain time to spray the fire extinguishing agent to the position of a fire point, fire caused by electric power burns rapidly, other switches in the switch cabinets are likely to burn, the fire extinguishing effect is poor, and the fire extinguishing equipment starts to respond only after the fire point in the switch cabinet becomes large, so that the response speed is too low.
Therefore, how to provide a switch cabinet with fire extinguishing function, so that the problems can be overcome. Is a problem that needs to be solved by the person skilled in the art.
