technical field

The utility model relates to the technical field of electric equipment, in particular to a heat dissipation switch cabinet.

Background technique

The switch cabinet is a kind of electrical equipment. The outside line of the switch cabinet first enters the main control switch in the cabinet, and then enters the sub-control switch. Each branch is set according to its needs. Such as instruments, automatic controls, motor magnetic switches, various AC contactors, etc., some also have high-voltage room and low-voltage room switch cabinets, high-voltage busbars, such as power plants, etc. load shedding.

The main function of the switchgear is to open and close, control and protect electrical equipment during the process of power generation, transmission, distribution and power conversion in the power system. The components in the switch cabinet are mainly composed of circuit breakers, disconnectors, load switches, operating mechanisms, transformers and various protection devices. There are many classification methods of switch cabinets. For example, according to the installation method of circuit breakers, it can be divided into removable switch cabinets and fixed switch cabinets; or according to the different cabinet structures, it can be divided into open switch cabinets, metal-enclosed switch cabinets, and metal Closed armored switchgear; according to different voltage levels, it can be divided into high-voltage switchgear, medium-voltage switchgear and low-voltage switchgear. It is mainly used in various occasions such as power plants, substations, petrochemicals, metallurgical steel rolling, light industry and textiles, factories and mines, residential quarters, and high-rise buildings.

The switchgear is classified according to the voltage level, usually AC1000V and below are called low-voltage switchgear, such as PGL, GGD, GCK, GBD, MNS; The medium voltage of AC10kV is called medium voltage cabinet, such as XGN15 type 10kV ring network cabinet.

According to the classification of voltage waveform, the switchgear is divided into: AC switchgear and DC switchgear.

According to the internal structure, the switchgear is divided into: withdrawable switchgear, such as GCS, GCK, MNS; fixed switchgear, such as GGD. According to the purpose, the switch cabinet is divided into: incoming line cabinet, outgoing line cabinet, metering cabinet, compensation cabinet (capacitor cabinet), corner cabinet, busbar cabinet.

When the switchgear is working, all kinds of electrical equipment will generate a lot of heat. If the excessive heat cannot be dissipated, it will easily lead to the aging and damage of the electrical circuits and electrical components inside the cabinet, and reduce the service life of the equipment. In order to solve the heat dissipation problem of switch cabinets, the mainstream products on the market are switch cabinets with air conditioners. This type of switchgear is expensive and consumes a lot of energy, and the volume of the switchgear becomes larger due to the installation of an air-conditioning system. However, for some small and medium switch cabinets, the heat generation is not very large compared with large switch cabinets. Obviously, the above-mentioned switchgear with air conditioner is not suitable for small and medium-sized switchgears. The prior art has not yet solved the heat dissipation problem of small and medium-sized switch cabinets.
