An integrated high-voltage bushing

Abstract

The invention discloses an integrated high-voltage bushing, which relates to the technical field of high-voltage power distribution ring network cabinet complete sets of equipment, including copper rods, temperature sensors, current sensors, voltage sensors and epoxy resin layers, and the epoxy resin layers are cast on copper rods. On the outside, the current sensor and voltage sensor are cast in the epoxy resin layer, the temperature sensor is embedded on the copper rod, and the output interface is reserved on the epoxy resin layer, and the current sensor and voltage sensor output signals through the output interface. The integrated high-voltage bushing of the present invention has the functions of monitoring current, voltage and temperature at the same time, is highly integrated, can meet users' requirements for standardization, integration and intelligence of distribution network equipment, and conforms to the trend of technological development.

Description

technical field [0001] The invention relates to the technical field of complete sets of high-voltage power distribution ring network cabinets, in particular to an integrated high-voltage bushing. Background technique [0002] At present, in the field of high-voltage power distribution ring network cabinet equipment, due to the traditional current transformers and voltage transformers in high-voltage power distribution ring network cabinets, they are large in size, difficult to install, and have many types. The big trouble also caused a lot of trouble for the operation and maintenance of the State Grid Corporation of China. Due to the low accuracy of traditional current transformers and voltage transformers, poor interchangeability, and heavy operation and maintenance workload, the State Grid Corporation urgently needs to coordinate the design of complete sets of technical conditions and testing requirements for primary and secondary equipment of the distribution network, so ...

[0002] At present, in the field of high-voltage power distribution ring network cabinet equipment, due to the traditional current transformers and voltage transformers in high-voltage power distribution ring network cabinets, they are large in size, difficult to install, and have many types. Big trouble, but also a lot of trouble for the operation and maintenance of the State Grid Corporation

Due to the low accuracy of traditional current transformers and voltage transformers, poor interchangeability, and heavy operation and maintenance workload, the State Grid Corporation urgently needs to coordinate the design of complete sets of technical conditions and testing requirements for primary and secondary equipment of the distribution network, so in 2016 In September 2009, the State Grid Corporation of China issued the "10kV Integrated Pole Transformer and Distribution Network Primary and Secondary Complete Set Typical Design and Testing Specifications", which clarified the standardization, integration and intelligent requirements of distribution network equipment, and vigorously advocated distribution network equipment "Complete-set-integration-intelligence"
