6/10kv direct pressure energy-saving high-pressure measuring tank

Abstract

The invention discloses a 6 / 10kV direct pressure energy-saving high-pressure measuring tank, consisting of a silastic dry composite bushing (1), a box body (2), a fixed base (10), a 10kV / 100V transformer (6), a switch power (8), a triphase grace electronic type multifunctional active meter (5), a GPRS wireless communication module (7) and a lightning arrester (4); the invention is characterized in that the upper parts of the front and rear side walls of the box body (2) are respectively fixed with an amorphous material current transformer (9); the upsides of the amorphous material current transformers (9) are both provided with isolated conversion circuit boards (3). Due to the adoption of amorphous material current transformers and high strength insulation material canning, the high-tension measuring tank has small overall volume and compact structure, is lightweight and free from the restrain of tension, can completely avoid stealing from the interior of equipment, has high overall precision, and is beneficial for the completeness and precision of the measurement.

Description

technical field [0001] The invention relates to a high-voltage electricity metering device, in particular to a small-volume, fully-sealed 6 / 10kV direct-pressure energy-saving high-voltage metering box for on-line monitoring and metering of high-voltage power supply lines and electric equipment. Background technique [0002] As the power system develops towards high voltage and large capacity, it is particularly important to ensure the safe operation and accurate measurement of power equipment. Once the abnormality of the line is not resolved in time, it will bring huge impact and loss to production. The high-voltage remote metering terminal is an important part of the on-line monitoring and metering of the distribution network. It can accurately measure and on-line monitor the single or multiple transformers of each branch user in the distribution network. At present, the metering methods used in the metering of 6 / 10kV power supply lines and electrical equipment are common h...

AI Technical Summary

Problems solved by technology

The above high-voltage metering terminal equipment has the following deficiencies: First, although the current high-voltage metering terminal has a multi-parameter metering display function, the measurement range and metering accuracy cannot meet the requirements at the same time. It is determined according to the load situation, and it only meets the accuracy requirements within a certain range. It cannot meet the accuracy range when measuring small loads, and the measurement range is narrow. For measurement equipment with a wide measurement range, its measurement accuracy is low and cannot meet the measurement requirements. Second, the existing high-voltage metering equipment, one equipment is limited to one voltage level, even if the current range can be wider, but the voltage range cannot be wider; third, the production cost is relatively high; fourth, the sealing The insulation performance is poor, and it is easy to cause damage due to human factors or natural factors. The high-voltage metering cabinets are mostly connected with the user's power distribution room. For some users, there may be a problem of power loss.
