Abstract
The utility model discloses an upper wire-outlet high-voltage switchgear which comprises a switchgear body. The switchgear body is internally provided with a column. The upper half art in the switchgear body in front of the column is successively provided with an instrument chamber and a circuit breaker chamber from top to bottom. The lower half part in the switchgear body is provided with a cable room which is communicated in a front-and-back direction. A busbar chamber is arranged above the back part of the cable chamber and is closely next to the top part and the column. A circuit breaker contact below the busbar chamber is arranged at the back side of the column behind the circuit breaker chamber. The bottom of the back part of the cable chamber is provided with a mutual inductor through a bracket. A busbar is connected with the mutual inductor and the circuit breaker contact. The back wall of the back cable chamber in the switchgear body is provided with a grounding switch. One end of the grounding switch is connected with the mutual inductor, and the other end is connected with the cable upwards. One side of the busbar chamber at the top part of the switchgear body in the back direction is provided with a cable outlet hole. The upper wire-outlet high-voltage switchgear has the following advantages: high convenience in mounting and maintenance, simple manufacture of the busbar between the circuit breaker chamber and the grounding switch, busbar saving, and damage reduction of electric power to a current transformer.
Description
Technical field:
The utility model relates to power distribution equipment, particularly a kind of installation and maintenance that makes things convenient for cable, the last outlet high-tension switch cabinet that improve equipment performance, reduces cost.
Background technology:
The mid-cabinet of existing high-voltage switch gear is to be respectively equipped with control room, breaker chamber, cable vault and bus-bar room in a cabinet.This structure is because current transformer has two kinds of mounting meanss, when level is lifted on below the bus-bar room, bring inconvenience to installation and maintenance, make troubles also can for when vertically being installed on the middle column in cable vault installation and maintenance, and all influence the processing of link and the function of reduction equipment.
Summary of the invention:
The purpose of this utility model is a kind of installation and maintenance that makes things convenient for cable of design, improves the last outlet high-tension switch cabinet of working (machining) efficiency and functions of the equipments.
The technical solution of the utility model is finished as follows, a kind of outlet high-tension switch cabinet of going up, it comprises a cabinet, the middle part is provided with column in cabinet, the first half is provided with the control room from top to bottom successively in the cabinet of column front, breaker chamber, the cable vault that Lower Half communicates before and after being provided with in cabinet, be close to the top in the back above the cable vault and column is equipped with a bus-bar room, it is characterized in that: the column rear side in the breaker chamber back is equipped with a contact of breaker below bus-bar room, with support an instrument transformer is installed in bottom, cable vault, back, between instrument transformer and contact of breaker, be connected with busbar, the rear wall of cable vault, back is equipped with an earthed switch in cabinet, earth connection one end of earthed switch connects instrument transformer, the other end of the earth connection stube cable that makes progress, the rear of cabinet top bus-bar room is provided with a cable outlet hole to a side.
The utlity model has installation, maintenance convenient, make simply with the busbar between breaker chamber and the earthed switch, and can save busbar, reduce electric power to the destruction of current transformer.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Describe embodiment in detail in conjunction with above accompanying drawing, it is that the middle part is equipped with a root post 5 from bottom to top in a cabinet 2, the first half is provided with control room 1 from top to bottom successively in the cabinet of column front, breaker chamber 3, the cable vault 4 that Lower Half communicates before and after being provided with in cabinet, be close to the top in the back above the cable vault and column is equipped with a bus-bar room 13, column rear side in the breaker chamber back is equipped with a contact of breaker 10 below bus-bar room, with support 6 instrument transformer 7 is installed in bottom, cable vault, back, between instrument transformer and contact of breaker, be connected with busbar 9, the rear wall of cable vault, back is equipped with an earthed switch 8 in cabinet, earth connection one end of earthed switch connects instrument transformer, the other end stube cable 11 that makes progress, bus-bar room back, cabinet top is provided with a cable outlet hole 12 to a side.The utility model is installed in current transformer on the support of cable vault, can save busbar installation length, reduce cost, not only convenient the installation and maintenance also can reduce electric power to the broken property of current transformer, improved the performance of equipment greatly.
