Ring main unit fault acquisition device and method

Abstract

The embodiment of the invention discloses a ring main unit fault acquisition device and method. The device comprises an outer frame. A fixed cavity is formed in the outer frame; an element cover is mounted in the fixed cavity; and the outer side wall of the element cover is provided with a collection mechanism which is connected with the inner wall of the fixed cavity and is used for collecting afault position. According to the invention, regional fault position acquisition can be carried out on the electrical elements through a temperature measurement matrix; during implementation, only an acquisition tape needs to be started, and the plurality of temperature sensors can perform one-to-one correspondence detection on the elements mounted in the element cover; then, early warning operation can be carried out on the electric elements through the detected temperature; once a element breaks down, the position of the element with the fault can be rapidly obtained, so that maintenance personnel can overhaul and maintain the element more conveniently and rapidly; meanwhile, once the circuit of the element is ignited, the fuse link can be fused, and a gas blocking cover can be opened atthe same time to make cooling and fire extinguishing gas can enter the element cover, and therefore, the loss is prevented from being further increased.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of power distribution network, and in particular to a device and method for collecting faults of a ring main unit. Background technique [0002] The ring network cabinet is a group of transmission and distribution electrical equipment (high-voltage switchgear) installed in a metal or non-metal insulated cabinet or made into an assembled interval ring network power supply unit. Its core part uses load switches and fuses. It has a structure Simple, small size, low price, improved power supply parameters and performance, and power supply security. In daily use, the most common fault in the distribution network is a short-circuit fault. [0003] At present, when detecting a short-circuit fault, most of them use a power distribution switch monitoring terminal (FTU for short) for detection, which has functions of remote control, telemetry, remote signaling, and fault detection.

Problems solved by technology

[0005] For this reason, the embodiment of the present invention provides a ring network cabinet fault acquisition device and method to solve the problem that in the prior art, it is impossible to perform early warning operations on the faults of the components in the cabinet, and it can only passively detect the faulty areas, resulting in It is more difficult for users to maintain in the later period, and when a large current flows through an aging circuit or component, it will generate a high temperature. However, due to the small internal space of the ring main unit, the heat is easy to accumulate, resulting in poor detection of the fault location. Accurate problems that take a long time to find
