Abstract

The invention discloses a solid insulation voltage transformer cabinet which comprises a cable boot connector which is installed inside a cabinet body, an isolation switch, an isolation switch actuation mechanism and the like, wherein a solid insulation layer is covered on the cable boot connector, the isolation switch, a lightning arrester connector and a voltage transformer, semi-conductive material is covered on the surface of the solid insulation layer, the voltage transformer is installed on an installation plate which is arranged on the top of the cabinet body, and the lightning arrestor connector is located between the voltage transformer and the isolation switch. Grading covers are respectively arranged inside the voltage transformer and the isolation switch, and each part are connected with each other in an inserted mode in the form of tapered plugs and jacks. Conical sealing pads are spaced at the inner portion of the contact surface of two ends of each junction, and the semi-conductive material which is covered on the surface of the above parts are conductively connected with the cabinet body through bolts and inserts. Compared with the prior art, the solid insulation voltage transformer cabinet solves the problems that the size of the existing solid insulation voltage transformer cabinet is larger in size, not high in insulation performance and the like.

Description

The solid insulation voltage transformer cabinet

Technical field

The present invention relates to high voltage electric power equip ment manufacturing technology field, particularly a kind of parts all adopt the voltage transformer cabinet of solid insulation.

Background technology

Existing looped network voltage transformer cabinet is commonly used have a kind of air type looped network voltage transformer cabinet in cabinet isolating switch and the link of primary line be as dielectric take air, earthed switch wherein, isolation switch contact are the cutter head formula, the alternate air insulation of utilizing.Owing to adopt air to carry out isolated insulation, alternate and relatively between all requires enough isolation distances, the one side insulation property are not high, can cause on the other hand cabinet overall dimension large, this just causes overall volume larger.

Summary of the invention

The object of the present invention is to provide a kind of solid insulation voltage transformer cabinet that solves the not high and larger problem of volume of existing looped network voltage transformer cabinet insulation property.

In order to address the above problem, the technical scheme of this solid insulation voltage transformer cabinet is: this solid insulation voltage transformer cabinet includes the cable shoes connector that is contained in the cabinet, isolating switch, the lightning arrester connector, voltage transformer, isolating switch operating mechanism etc.At described cable shoes connector, described lightning arrester connector, the outside of described voltage transformer and described isolating switch all is coated with solid insulating layer except the connectivity port, be provided with semiconductive material on described solid insulating layer surface, described voltage transformer is installed on the mounting panel at cabinet top; Described lightning arrester connector is between described voltage transformer and described isolating switch; Fixed contact place at described isolating switch is provided with grading shield.

In the technique scheme, technical scheme can be more specifically: described cable shoes connector, and described isolating switch, described lightning arrester connector, the connection between the described voltage transformer all is to be connected with jack by cone-shaped plug; Contact-making surface between the described solid insulating layer at each two ends, junction is bonded to each other near the part of outer surface, makes the described semiconductive material layer between two connectors realize that also conduction connects, and is separated with conical gasket between the inner part of described contact-making surface.

Further: by bolt, cone pad and inserts are with described body insulation isolating switch and described lightning arrester connector, and the described semiconductive material layer on described lightning arrester connector and described voltage transformer surface is communicated with, and is connected with described cabinet.

Because adopt technique scheme, the present invention compared with prior art has following beneficial effect:

1, the present invention has compact conformation, and small volume is convenient for installation and maintenance.

2, good insulation preformance of the present invention is reliable, and adaptive capacity to environment is strong.
