Rainproof cover for oil level gauge of transformer oil conservator

Abstract

The invention provides a rain cover for an oil level indicator of a transformer oil conservator and belongs to the technical field of transformer protection facilities. The rain cover comprises a first supporting frame, a second supporting frame, rain cover bodies, a power supply mechanism, a driving mechanism and an illumination component, wherein the rain cover bodies are in a fan shape, and through the arrangement of the rain cover bodies which are mutual hinged, the unfolding angle of the rain cover is adjustable; and the arranged power supply mechanism can charge a storage battery in thedaytime and can provide a power source for illumination of the illumination component when the oil level indicator is checked at night. Therefore, the technical problems that circuit insulation is poor because the oil level indicator of the oil conservator is prone to be eroded by rainwater, readings of the oil level indicator cannot be seen clearly because light is weak at night, and measurementis not accurate are solved. The rain cover achieves the technical effects that the unfolding angle of the rain cover is adjustable, the oil level indicator can be illuminated, measuring operation efficiency is improved, and circuit insulation performance is protected.

Description

technical field [0001] The invention belongs to the technical field of transformer protection facilities, and more specifically relates to a rainproof cover for an oil level gauge of a transformer oil conservator. Background technique [0002] With the development of the economy, the power consumption of the society is increasing, and the number of transformers is also increasing. The oil conservator is an important part of the transformer, and the oil level gauge for detecting the cooling oil in the oil conservator is also indispensable. However, the oil level gauge has been exposed outdoors for a long time, and the secondary cable junction box of the oil level gauge is not well sealed. It has been affected by rain erosion for a long time, and the oil level gauge is greatly affected, and needs to be replaced from time to time. The cost of the oil level gauge increases; and rain erosion will cause poor insulation of the electrical circuit, causing the main transformer to tri...
