Environmental protection type high-voltage switchgear

Abstract

The invention discloses an environment-friendly high-voltage switchgear, which comprises a cabinet body. The cabinet body is composed of a low-voltage instrument room, a circuit breaker handcart room, a high-voltage bus room, a high-voltage cable room, and a small bus room. Metal partitions are used between the rooms Completely closed, the handcart room of the circuit breaker is equipped with a handcart circuit breaker, the high-voltage bus room is equipped with an upper contact box, and the high-voltage cable room is equipped with a lower contact box, a current transformer, and a grounding switch. The device is respectively connected with the static contacts in the upper contact box and the lower contact box, the static contacts in the upper contact box are connected with the main busbar through the upper lead busbar, the main busbar is arranged in the wall bushing, and the The wall bushing passes through and is fixed on the cabinet body, the static contact in the lower contact box is connected to the current transformer through the lower busbar, and the current transformer is connected to the grounding switch. All insulating parts of the present invention are made of PA66+glass fiber, which is used to replace traditional epoxy resin insulating parts, and fully meets the electrical performance of high-voltage switchgear.

Description

technical field [0001] The invention relates to an environment-friendly high-voltage switchgear, which belongs to the field of electric equipment. Background technique [0002] In the power transmission and transformation system, the switchgear is an important part, which realizes the transmission and distribution of electric energy. Epoxy resin insulation products have long been used for switchgear insulation. The waste generated in the production process of epoxy resin will change the pH of water and soil; epoxy resin casting insulation products become "stubborn" garbage of nature because epoxy resin cannot be degraded after they are scrapped. If the epoxy resin is burned, a large amount of carcinogens will be produced, which will endanger human health and pollute the environment. At the same time, epoxy resin cast insulation products generally adopt vacuum casting molding technology, and the pretreatment, mixing, pouring and curing conditions of raw materials must be st...
