Description

Heat dissipation type high tension switchgear

Technical Field

The utility model relates to a power equipment technical field, concretely relates to heat dissipation type high tension switchgear.

Background

The high-voltage switch cabinet is internally provided with various switch devices in use and realizes related operations by combining cables led into the cabinet body. The leading-in mode of the cable is divided into an upper incoming line and a lower incoming line, namely the cable is led into the cabinet body from the top of the cabinet body from the cable trough hung above the cabinet body to form the upper incoming line, and the cable is led into the cabinet body from the bottom of the cabinet body to form the lower incoming line from the trench. The temperature that current high tension switchgear internal plant work produced is higher in the use, relies on the natural convection heat to give off at cabinet internal portion slower, and the high temperature leads to the internal plant to damage easily, and work efficiency is low, and the security is lower. Convection heat dissipation is generally enhanced by the use of fans. In order not to influence the incoming line position of the cable, the fan is generally arranged around the cabinet body. For example, patent publication No. CN 209389538U discloses a heat dissipation type high voltage cabinet, which utilizes two fans arranged at the back of a cabinet body and a plurality of groups of fans located at the side of the cabinet body to dissipate heat of equipment in the cabinet body. Although the design can meet the requirement of heat dissipation of switch equipment in the cabinet body, the incoming line position of the cable is not influenced, but the aerodynamic principle is not met, and natural convection is not well utilized. And the number of fans used is large, which is inconvenient for routine maintenance. Especially, the fans arranged on the side surfaces of the cabinet body can mutually influence each other when a plurality of high-voltage cabinets are arranged side by side, so that the heat dissipation efficiency is reduced.

The utility model discloses introduce the cross-flow fan that prior art mainly was applied to the air conditioner field, utilize patent publication number: CN 2376554Y discloses a technical scheme, which introduces a cross-flow fan to the field of high-voltage switch cabinets and the like. Thereby avoiding the fans used for heat dissipation in the prior art to occupy most of the top space of the cabinet body, thereby influencing the erection of the upper wiring cables. When the air outlet of the heat radiator at the top of the cabinet body and the V-shaped air inlet near the bottom of the cabinet body are combined with the cabinet body which is sealed relatively, a space similar to a chimney is formed. Cold air enters the cabinet body from a V-shaped air inlet on a back plate at the bottom of the cabinet body, is heated by a heating device in the cabinet body and then gradually rises, when the cold air reaches the position near the top of the cabinet body, because the bottom of the heat radiating device is provided with a heat radiating device air inlet communicated with the top of the cabinet body, the cold air is quickly extracted from the cabinet body under the suction action of a cross flow fan in the heat radiating device at one end of a door panel at the top of the cabinet body, and finally hot air is discharged to the outside of the cabinet body from an air outlet. The accelerated extraction of the hot air on the upper part of the cabinet body can drive the V-shaped air inlet at the bottom of the cabinet body to introduce cold air, so that the air flow which flows through the cabinet body quickly is formed under the drive of the cross flow fan to take away the heat in the cabinet body, and the equipment is cooled quickly.

The utility model has the advantages as follows: different from the traditional high-voltage switch cabinet, the technical scheme adopts the air outlet of the heat dissipation device positioned at one end of the top of the cabinet body and combines the V-shaped air inlet positioned at the bottom of the cabinet body to dissipate heat for equipment. Because this technical scheme does not set up air inlet or gas vent in the cabinet body left and right sides, so can not influence each other when a plurality of cabinet bodies set up side by side. This technical scheme has fully considered the possible inlet wire mode of cable, no matter go up the inlet wire or down the inlet wire and all left sufficient space. The V-shaped air inlet is arranged below the back plate of the cabinet body and the air outlet of the cross-flow fan in the heat dissipation device arranged above the door plate, and a diagonal design is formed inside the cabinet body, so that the path of convection gas in the cabinet body is increased, heat generated by equipment inside the cabinet body is taken away to the maximum extent, and the effect of quickly dissipating heat of the equipment inside the cabinet body is achieved.
