Embodiment Construction

[0014] Examples such as figure 1 As shown in 1, a modular inflatable switchgear, including a cabinet body 1, also includes a low-voltage instrument room arranged on the upper left side of the cabinet body, a circuit breaker room arranged on the upper right side of the cabinet body, and a top arc is arranged above the circuit breaker room Collection channel; there is a bus room at the lower left of the cabinet, and a cable room at the lower right; there is a bottom arc collection channel under the bus room; the bus room and the circuit breaker room are independent and separable modules, which are filled with insulating gas.

[0015] The bus chamber 5 and the circuit breaker chamber 3 are independent and separable modules, that is, independent and separable closed chambers, which are filled with N2, SF6 or a mixture of the two at a specific pressure. A pressure relief device is provided in the bus chamber 5 . The low-voltage instrument room is equipped with two gas density mete...

Abstract

The invention discloses a modular inflatable switchgear, which includes a cabinet body, a low-voltage instrument room arranged on the upper left side of the cabinet body, a circuit breaker room arranged on the upper right side of the cabinet body, and a top arc collector is arranged above the circuit breaker room Channel; the lower left of the cabinet is provided with a bus room, and the lower right is provided with a cable room; the lower part of the bus room is equipped with a bottom arc collection channel; the bus room and the circuit breaker room are independent and separable modules, which are filled with insulating gas. The invention can effectively solve the problems of unreasonable structure and unreliable performance of the existing modularized inflatable switchgear.

Description

technical field [0001] The invention relates to a modular inflatable switch cabinet. Background technique [0002] With the development of the country's society and economy, especially the continuous deterioration of the environment, the power and power equipment industry is developing towards the sustainable direction of integration, intelligence, green environmental protection, energy saving and consumption reduction, and the development and use of "resource-saving, environment-friendly" Type" products are imminent. [0003] It is very likely that SF6 gas will be included in the ban list in 2020, especially medium-voltage switchgear should bear the brunt. Therefore, the National Development and Reform Commission has included the research and development of 40.5kV SF6-free gas insulated switchgear in the 2010 national key support research and development project recommendation catalog. Therefore, it is of epoch-making significance for power equipment manufacturers to deve...
