Intelligent demarcation charge control pole-mounted circuit breaker

Abstract

The invention provides an intelligent demarcation charge control pole-mounted circuit breaker which comprises a first circuit breaker box body and a first arc-shaped groove, the first arc-shaped groove is formed in the middle of the front end face of the first circuit breaker box body, a first electric telescopic plate is slidably connected into the first arc-shaped groove, and a first spray head is fixedly installed in the first arc-shaped groove. The connecting columns are fixedly connected to the four corners of the front end face of the first circuit breaker box body, the fixing grooves are formed in the connecting columns, the protection plates are fixedly connected to the front end faces of the connecting columns, and the limiting grooves are formed in the four corners of the protection plates. The elastic contact piece is elastically connected to the interior of the protection plate, one side of the side end face of the first circuit breaker box is fixedly connected with a control cabinet, and one side, deviating from the side end face of the control cabinet, of the first circuit breaker box is slidably connected with a second circuit breaker box in a clamped mode, and the problems that a traditional pole-mounted circuit breaker is tedious in installation, and a support needs to be independently installed during installation are solved.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to an intelligent demarcation charge control pole-mounted circuit breaker. Background technique [0002] A pole-mounted circuit breaker is a circuit breaker that is installed and operated on a pole. The power research level and manufacturing technology of various circuit breakers have made great progress. Vacuum circuit breakers are not limited to medium-voltage power grids, but are developing towards high voltage and large capacity. Sulfur hexafluoride circuit breakers have many Advantages, such as strong opening capacity, many continuous breaking times, frequent operation, low operating noise, no fire hazard, etc., it is a very good oil-free equipment. [0003] The circuit breaker on the intelligent demarcation fee control column is composed of an integral casting dry-type high-voltage metering box and an intelligent demarcation switch. It is suitable for electric energy meterin...

AI Technical Summary

Problems solved by technology

[0004] However, there are the following problems in the actual use of the existing circuit breaker on the control column of the intelligent boundary fee: the existing circuit breaker on the control column of the intelligent boundary fee is provided with a separate electric control box, and the separate installation of the box and the circuit breaker is relatively cumbersome. At the same time, the existing circuit breaker on the intelligent demarcation fee control column often needs to install the fixed bracket separately first, and the installation of the circuit breaker is more cumbersome after the fixed bracket is installed, and the bracket will also increase the transportation cost of the device, which greatly increases The labor cost of equipment installation, and the use of brackets also faces various problems of rust maintenance and replacement, which is inconvenient
