Description

An extension device for an outdoor oil-immersed transformer respirator

technical field

The utility model relates to the field of transformers, in particular to an extension device of an outdoor oil-immersed transformer respirator.

Background technique

At present, the outdoor oil-immersed transformer is widely used, and the installation position is relatively high, and the respirator installed on the transformer is relatively close to the live part. Replacing silicone oil-immersed transformer respirator is a common task for transformer maintenance. However, maintenance personnel need to use ladders to climb up to work when replacing silicone, which is very inconvenient. At the same time, there are safety hazards such as electric shock and falling from high altitudes. At present, there is no practical and effective method to solve this problem.

Utility model content

The purpose of this utility model is to provide an extension device for an outdoor oil-immersed transformer respirator, so as to solve the problems raised in the above-mentioned background technology.

In order to achieve the above object, the utility model provides the following technical solutions:

An extension device for an outdoor oil-immersed transformer respirator, including an extension tube connected to the transformer respirator and a respirator, the respirator is connected to the transformer respirator through the extension tube, and the respirator is installed on the extension through a connecting flange On the pipe, a control valve is installed on the extension pipe, a protective box is installed outside the respirator, and a plurality of ventilation holes are opened on the outer wall of the protective box.

As a further solution of the utility model: the ventilation holes on the side wall of the protective box are set at an inclination of 30-45°.

Compared with the prior art, the beneficial effects of the utility model are: the utility model has simple principle and structure, convenient construction and installation, and strong practicability, which can greatly facilitate the work of maintenance personnel to replace the silica gel of the transformer respirator, and improve the efficiency of the work. Safety; at the same time, it is conducive to the heat dissipation of the respirator and ensures the normal operation of the device.
