Power distribution network pole-mounted automatic switch adopting electronic sensor

Abstract

The invention discloses a power distribution network pole-mounted automatic switch adopting an electronic sensor. The switch comprises a switch device, a feeder terminal and a power supply voltage transformer which are mutually connected through cables, wherein the switch device comprises a switch body, an electronic voltage sensor and an electronic current sensor, and the electronic voltage sensor and the electronic current sensor are used for collecting voltage and current state information of the switch body. The power distribution network pole-mounted automatic switch has the technical effects that by utilizing the design of the power distribution network pole-mounted switch simultaneously having measurement, protection and metering functions, the operation and maintenance quality andefficiencies of the pole-mounted switch can be effectively improved, the field mounting and debugging are convenient, and the power failure time is greatly shortened; by adopting the electronic sensor, the current and voltage sampling precisions are increased to metering levels, so that the switch can meet the requirements on fault detection, measurement, metering and the like; by adding distribution network damage management and feeder automation functions, the operation level of distribution equipment is increased; and primary and secondary equipment are connected through an aviation connector, so that the compatibility and the sealing property of an interface are improved.

Description

technical field [0001] The invention relates to an automatic switch on a power distribution network column using an electronic sensor. Background technique [0002] With the development of computer and digital technology, the power system has begun to turn to automation, digitization, and intelligence, and the demand for switchgear has gradually changed to modularization, miniaturization, multi-function, and maintenance-free. The current automatic design and transformation of pole-mounted switches in the distribution network mainly has the following problems: First, the interface of the secondary equipment does not match, and the compatibility, scalability, and interchangeability are poor; the responsibility disputes between the manufacturers of the first and secondary equipment are not clear; there is a lack of line loss measurement Function; there is equipment condensation; traditional electromagnetic current and voltage sensors have a small measurement dynamic range and n...
