Embodiment Construction
[0040] Embodiments of the gas-insulated metal-enclosed switch of the present invention will be further described below in conjunction with the accompanying drawings.
[0041] The present invention is introduced by taking the gas-insulated metal-enclosed switch used in C-GIS as an example. In other embodiments, the gas-insulated metal-enclosed switch can also be the GIS used in the three-phase common cylinder of the main bus, or the three-phase common cylinder. GIS or composite or hybrid GIS.
[0042] like Figure 1-5 As shown, the gas-insulated metal-enclosed switch includes a sealed housing 100, and the isolating switch is arranged in the sealed housing 100. In this embodiment, the isolating switch includes a static contact 3 and a moving contact that is plugged and adapted to the static contact 3. 1. The static contact 3 is fixed in the sealed housing through the insulating base 5. Specifically, the lower end of the insulating base 5 is provided with a connecting flange, an...

The invention provides a gas-insulated metal-enclosed switch. The gas-insulated metal-enclosed switch comprises a seal shell, an insulating base is fixedly arranged in the seal shell, a static contactis fixedly arranged on the insulating base, and the static contact is connected with a bus; the gas-insulated metal-enclosed switch further comprises a moving contact, the moving contact is matched with the static contact, a heat pipe and a heat dissipation piece are further arranged in the seal shell, wherein one end of the heat pipe is connected with the insulating base, the other end of the heat pipe is connected with the heat dissipation piece, part of the heat dissipation piece extends out of the seal shell and is in sealing fit with the seal shell at the extending position, the heat pipe absorbs heat of the insulating base and transmits the heat to the heat dissipation piece, and the heat dissipation piece dissipates the heat to the outside of the seal shell; the heat pipe can quickly transmit the heat of the insulating base to the heat dissipation piece, and part of the heat dissipation piece extends out of the seal shell, so that the heat can be dissipated out of the seal shell, the heat dissipation of the insulating base can be accelerated, the temperature of the static contact is indirectly reduced, and the temperature of the static contact is prevented from exceeding the standard.
Description
technical field [0001] The invention relates to a gas-insulated metal-enclosed switch. Background technique [0002] Box-type gas-insulated metal-enclosed switchgear (C-GIS for short) is a kind of power transmission and distribution system used for 10-35kv or higher voltage to receive or distribute electric energy and to control the power system under normal operation and fault conditions. A new type of switchgear with protection, measurement, monitoring, communication and other functions, C-GIS is a kind of GIS. [0003] C-GIS metal-enclosed switchgear has been widely used in power system distribution and high-speed railway distribution station construction in the medium voltage field due to its small size and compact size. However, the primary conductive main circuit of C-GIS metal-enclosed switchgear is sealed in a closed air chamber, the heat of the main conductive circuit cannot be well exchanged with the outside air, and because the interior is airtight, the airflow h...
