Embodiment Construction

[0016] see figure 1 The specific structure is: the circuit breaker of the solid insulation switchgear and the three-position isolating / grounding switch are combined as one, and share a solid insulating shell, and the conductive connectors between the circuit breaker and the three-position isolating / grounding switch are also solidly sealed In the insulating case, the integrated circuit breaker and the three-position isolating / grounding switch are fixed on the box, the bus bar is arranged above the three-position isolating / grounding switch, and the current mutual inductance fixed on the box is arranged below. device.

[0017] The bus bar is a T-shaped structure, the first and second ends are fixed on the box body, the third end is connected to the three-position isolation / grounding switch, the circuit breaker and the current transformer are connected with a connecting conductor, and the cable is connected to the current transformer , The bus bar, connecting conductors and cable...

Abstract

The invention relates to solid insulation switch equipment, which consists of a box body, a circuit breaker, a three-station insulation/grounding switch, a bus, a connecting conductor, a current transformer and a cable, wherein the circuit breaker and the three-station isolation/grounding switch of the solid insulation switch equipment are combined into a whole and share one solid insulation casing, because a conducting connecting element between the circuit breaker and the three-station insulation/grounding switch is also fixed and encapsulated, parts, movable elements and assembly links are reduced, the equipment operation safety is improved, meanwhile, the space dimension between the circuit breaker and the three-station insulation/grounding switch is greatly reduced, the size of the equipment is smaller, in addition, other elements are also covered by solid insulation materials as outer insulation, in addition, a layer of semiconducting material is sprayed and coated on the surface of the solid insulation materials to be used as a grounding layer, the equipment insulation performance is excellent, safety and reliability are realized, the insertion type connection is adopted between the elements, and the assembly, the regulation, the overhaul and the maintenance are more convenient.

Description

technical field [0001] The invention relates to a medium voltage switchgear, in particular to a solid insulated switchgear. Background technique [0002] The insulation performance and volume of medium-voltage switchgear are two main factors restricting the development of medium-voltage switchgear. Around the above two main factors, the development of medium-voltage switchgear technology has experienced air insulation-composite insulation-gas insulation-solid insulation stage. Solid insulated switchgear is a new type of switchgear developed in recent years. It has the advantages of small size, high reliability, greatly reduced maintenance frequency, and extended maintenance cycle. It has broad application prospects and is also an inevitable trend in the development of the switch industry. . [0003] The existing solid insulated switchgear, circuit breaker and three-position isolating / grounding switch are independent modules, which have the advantage of flexible modular com...
