Abstract

A voltage transformer cabinet comprises a cabinet body (1), a fuse (2), a lightning arrester (3) and a voltage transformer (4), wherein a busbar chamber (11), a circuit breaker chamber (12), a primary cable chamber (13), a secondary cable chamber (14) and an instrument chamber are arranged in the cabinet body (1); the fuse (2) and the lightning arrester (3) are mounted in the circuit breaker chamber (12) via a circuit breaker handcart (21); the voltage transformer (4) is mounted in a first cable chamber (13); and one end of the fuse (2) is connected in parallel with the lightning arrester (3) on an upper contact arm of the circuit breaker handcart (21) while the other end thereof is connected with a lower contact arm of the circuit breaker handcart (21). The voltage transformer cabinet has safety and reliability, and various types of voltage transformers can be selected according to different requirements.

Description

The voltage transformer cabinet
Technical field
The utility model relates to and a kind of system high voltage is become the equipment of the low-voltage of standard, particularly a kind of voltage transformer cabinet.
Background technology
Present 10kV voltage transformer cabinet mainly is that the 100V voltage of standard is used for various protective devices and the instrument components and parts measure, measure, protect with 10kV high-voltage variable in the system.
Present voltage transformer cabinet shown in Fig. 4-5, it comprises cabinet 1, fuse 2, lightning arrester 3 and voltage transformer 4, is provided with bus-bar room 11, breaker chamber 12, cable vault 13, secondary cable chamber 14 and a control room 15 in the cabinet 1; Fuse 2 is installed in the breaker chamber 12 by handcart with voltage transformer 4; lightning arrester 3 is installed in the secondary cable chamber 14 by handcart; high voltage source in the bus-bar room 11 is transported to lightning arrester 3 in fuse 2, voltage transformer 4 and the secondary cable chamber 14 in the breaker chamber 12 by contact box on the median septum and bus, to finish high-tension metering, measurement, overvoltage protection.This employing voltage transformer handcart and bus lightning arrester handcart be the voltage transformer cabinet of combined arranging mode up and down; because two handcarts are modes arranged side by side; the whole bus of bus protection of arrester; the voltage transformer so should after the bus lightning arrester puts into operation, just can put into operation; prevent from voltage transformer to be caused damage because of the bus overvoltage; can only put into operation according to the priority program according to present this mode; and fuse 2 is combined into a handcart with voltage transformer 4 and is installed in the breaker chamber 12; can not select different voltage transformer 4 for use according to different schemes and designing requirement, that can only limit to selects the voltage transformer that is fit to be installed on the handcart for use.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art and a kind of voltage transformer cabinet is provided, and it can select different voltage transformers for use with designing requirement flexibly according to different schemes.
The technical solution of the utility model is: a kind of voltage transformer cabinet, and it comprises cabinet, fuse, lightning arrester and voltage transformer, is provided with bus-bar room, breaker chamber and a cable vault in the cabinet; Fuse and lightning arrester are installed in the breaker chamber by circuit breaker cart; Voltage transformer is installed in cable vault.
The further technical scheme of the utility model is: the last contact arm of circuit breaker cart is connected with high voltage bus in the bus-bar room by contact box and copper bus-bar, one end of fuse and lightning arrester are connected in parallel on the last contact arm of circuit breaker cart, the other end of fuse is connected on the following contact arm of circuit breaker cart, and the following contact arm of circuit breaker cart is connected with the end of incoming cables of voltage transformer with cable by contact box, copper bus-bar.
The utility model compared with prior art has following characteristics:
1, is series relationship between circuit breaker cart and the voltage transformer, must operates in order, like this safety and reliability;
2, simultaneously because voltage transformer is to be arranged separately in cable vault, can select different classes of voltage transformer for use according to different requirements like this.
Below in conjunction with the drawings and specific embodiments detailed structure of the present utility model is further described.
