Abstract

The utility model discloses a kind of novel solid ring main unit, comprise housing and be located at vacuum circuit-breaker arc extinguishing chamber, isolating switch moved end moving contact seat and the quiet end of isolating switch in housing, vacuum circuit-breaker arc extinguishing chamber is horizontal positioned, its left end is by insulating sleeve stube cable interface, its right-hand member connects isolating switch moved end moving contact seat by conductor, isolating switch moved end moving contact seat is provided with moveable isolate conductive bar, isolate conductive bar can realize closing operation with the quiet end in contact of isolating switch, and the quiet end of isolating switch is by the extendible bus of bus insulation sub-connection.A high-voltage charged body is coated in housing by the utility model completely, and bus and cable adopt socket connection, and entirety realizes totally-enclosed all insulation.

Description

A kind of novel solid ring main unit
Technical field
The utility model relates to a kind of ring main unit structure.
Background technology
Array switch and relevant live part entirety adopt epoxy resin to pour into a mould by solid insulation exactly, have manufactured solid insulation power supply unit by automatic pressure gel Technology design.This kind of power supply unit, without the discharge of any noxious substance, meets environmental requirement completely.But due to pouring technology and quality control aspect, the change of external environment, the factor of temperature rise causes epoxy to ftracture, and causes failure of insulation, can cause insulation breakdown, affects the normal operation of switch cubicle.
Summary of the invention
For solving the problems referred to above that existing ring main unit exists, the utility model patent provides a kind of novel solid ring main unit, and its technical scheme taked is:
Comprise housing and be located at vacuum circuit-breaker arc extinguishing chamber, isolating switch moved end moving contact seat and the quiet end of isolating switch in housing, vacuum circuit-breaker arc extinguishing chamber is horizontal positioned, its left end is by insulating sleeve stube cable interface, its right-hand member connects isolating switch moved end moving contact seat by conductor, isolating switch moved end moving contact seat is provided with moveable isolate conductive bar, isolate conductive bar can realize closing operation with the quiet end in contact of isolating switch, and the quiet end of isolating switch is by the extendible bus of bus insulation sub-connection.
A high-voltage charged body is coated in housing by the utility model completely, and bus and cable adopt socket connection, and entirety realizes totally-enclosed all insulation, overall structure is that assembly type connects, cost is low, can realize modularization, is applied in transformer station, switchgear house, outdoor feeder pillar, switching station.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, vacuum circuit-breaker arc extinguishing chamber 2, isolating switch moved end moving contact seat 4 and the quiet end 7 of isolating switch are located in housing 8, vacuum circuit-breaker arc extinguishing chamber 2 is in horizontal positioned, its left end is by insulating sleeve 1 stube cable interface, its right-hand member connects isolating switch moved end moving contact seat 4 by conductor 3, isolating switch moved end moving contact seat 4 is provided with moveable isolate conductive bar 5, isolate conductive bar 5 can contact with the quiet end 7 of isolating switch and realize closing operation, and the quiet end of isolating switch 7 connects extendible bus by bus-bar insulator 6.
