10kv high-voltage integral electric energy metering device

Abstract

The invention relates to a 10kV high-voltage integral electric energy metering device which comprises a metering cabinet and a fuse protector handcart, wherein a fuse protector chamber, a bus chamber, a voltage transformation chamber, a bus coupler chamber and a metering chamber which are separated by partition plates are arranged in the metering cabinet, the metering chamber, the fuse protector chamber and the voltage transformation chamber are sequentially arranged at the front part of the metering cabinet from top to bottom, the bus chamber and the bus coupler chamber are sequentially arranged at the rear part of the metering cabinet from top to bottom, and the fuse protector handcart is arranged in the fuse protector chamber. Compared with the prior art, the device has the advantages of improvement on work efficiency, improvement on factorization skill, reduction in the comprehensive error of the metering device, excellent mechanical strength and the like.

Description

technical field [0001] The invention relates to an electric energy metering device, in particular to a 10kV high-voltage integrated electric energy metering device. Background technique [0002] At present, the standardized design of 10kV electric energy metering devices stipulates the use of split-type high-voltage metering cabinets, that is, the voltage and current transformers for metering are not installed in the metering cabinets, but are installed separately in high-voltage switch cabinets. The existing split-type high-voltage metering cabinets Mainly PJ2FK metering cabinet. PJ2FK metering cabinet is standard configuration. In addition to the PJ2FK metering cabinet, there are also some metering cabinets that were used earlier and metering cabinets purchased by users, and there are even cases where metering equipment is installed on the meter board. These metering cabinets that do not meet the standard configuration have poor safety, closed Problems such as poor perfo...

AI Technical Summary

Problems solved by technology

In addition to the PJ2FK metering cabinet, there are also some metering cabinets that were used earlier and metering cabinets purchased by users, and there are even cases where metering equipment is installed on the meter board. These metering cabinets that do not meet the standard configuration have poor safety, closed Problems such as poor performance, poor scalability and poor uniformity

[0003] The first is poor security

Most metering cabinets are likely to cause safety accidents during meter adjustment and weekly inspection, resulting in personal injury and equipment damage, especially metering equipment installed on the meter board, there is no material insulation between strong and weak currents, and there are many exposed electrical parts , there are many security risks

[0004] followed by poor closure

For self-purchased metering cabinets and meter panels, users can directly access the entire metering circuit, and the terminals of the secondary circuit are not equipped with anti-theft covers, and some circuits still have exposed parts, so it is easy to implement electricity theft

[0005] Third, poor scalability

According to the standard design regulations of the electric energy metering device of the power company, the
