Abstract
The utility model relates to a device specially used for maintaining a transformer, which comprises a main silica gel tank and an auxiliary silica gel tank, wherein the main silica gel tank and the auxiliary silica gel tank are respectively and internally provided with silica gel in a sealing way; a pipeline arranged at the upper end of the main silica gel tank is provided with a main valve, and the lower end of the main silica gel tank is connected with a breathing apparatus; a pipeline arranged at the upper end of the auxiliary silica gel tank is provided with an auxiliary valve, and the lower end of the auxiliary silica gel tank is connected with the breathing apparatus; pipelines respectively arranged at the upper ends of the main valve and the auxiliary valve are connected with the transformer, and are respectively connected with two branches of a three-way flange; and the branch at the upper end of the three-way flange is connected with the transformer by a breathing flange of the transformer. The device can avoid the transformer quitting gas protection when the breathing apparatus or the silica gel of the transformer is replaced, so that the transformer can always run safely and stably under total protection.
Description
Technical field
The utility model relates to mechanical field, and particularly the maintenance unit of transformer in the power equipment specifically is the isolated plant that a kind of transformer is safeguarded.
Background technology
For avoiding transformer oil to make moist, high-power transformer is equipped with respirator and hygroscopic agent, and in transformer its hygroscopic agent meeting variable color after operation a period of time, prompting is in time changed, and influences transformer work to avoid transformer insulation oil to make moist.When changing silica gel, will the inside main protection (protection) of transformer be withdrawed from present, make transformer lose main protection like this, the equipment that loses protection is just just as there not being the automobile of brake, and is abnormally dangerous, the operation of the serious threat stabilization of power grids.
Summary of the invention
The isolated plant that the purpose of the utility model is to provide a kind of transformer to safeguard, described this isolated plant will solve and when changing transformer respirator or silica gel, need withdraw from main protection in the prior art and make the unsafe technical problem of operation of power networks.
The purpose of the utility model realizes through following technical scheme: it is characterized in that: it comprises main silica gel jar and secondary silica gel jar; Sealing is provided with silica gel in main silica gel jar and the secondary silica gel jar; The pipeline of main silica gel jar upper end is provided with main valve, and main silica gel jar lower end links to each other with respirator, and the pipeline of secondary silica gel jar upper end is provided with auxiliary-valve; Secondary silica gel jar lower end is connected with respirator, and main valve is connected with transformer with the pipeline of auxiliary-valve upper end.
Main valve is connected with two branches of a threeway flange respectively with the pipeline of auxiliary-valve upper end, and the upper end branch of described threeway flange is connected with transformer through the breathing flange of transformer.
The utility model is compared with prior art, and its effect is actively with tangible.The isolated plant that this transformer is safeguarded is owing to set up a secondary silica gel jar and it is connected through threeway with main silica gel jar, when normally moving by the work of downside master respirator, in case during main respirator silica gel variable color replacing; Open side three ports, load onto backup breaths device (secondary respirator), the open auxiliary valve; Close main valve, pull down main respirator then, with the lower flange mouth of main respirator with Polypropylence Sheet stifled on; Load onto after changing silica gel or respirator, open main valve, close auxiliary-valve again; Pull down backup breaths device (secondary respirator), shutoff upside mouth.So just avoided transformer when changing respirator or silica gel, to withdraw from protection, transformer is moved under safety and stability, full guard all the time.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Through embodiment the utility model is done further explain below in conjunction with accompanying drawing.
As shown in Figure 1.In the present embodiment; It is characterized in that: it comprises main silica gel jar 1 and secondary silica gel jar 2, and main silica gel jar 1 is provided with silica gel with secondary silica gel jar 2 interior sealings, and the pipeline of main silica gel jar 1 upper end is provided with main valve 3; Main silica gel jar 1 lower end links to each other with respirator 5; The pipeline of secondary silica gel jar 2 upper ends is provided with auxiliary-valve 4, and secondary silica gel jar 2 lower ends are connected with respirator 5, and the pipeline of main valve 3 and auxiliary-valve 4 upper ends is connected with transformer 6.
The pipeline of main valve 3 and auxiliary-valve 4 upper ends is connected with two branches of a threeway flange 7 respectively, and the upper end branch of described threeway flange 7 is connected with transformer 6 through the breathing flange of transformer 6.
By the work of downside master respirator,, load onto backup breaths device (secondary respirator) during normal operation in case when main respirator silica gel variable color is changed, open side three ports; The open auxiliary valve is closed main valve, pulls down main respirator then; The lower flange mouth of main respirator is blocked up with Polypropylence Sheet, load onto behind replacing silica gel or the respirator, open main valve; Close auxiliary-valve again, pull down backup breaths device (secondary respirator), shutoff upside mouth.So just avoided transformer when changing respirator or silica gel, to withdraw from protection, made transformer operation under safety and stability, power protection all the time.
Claims (2)
1. the isolated plant safeguarded of a transformer; It is characterized in that: it comprises main silica gel jar and secondary silica gel jar, and sealing is provided with silica gel in main silica gel jar and the secondary silica gel jar, and the pipeline of main silica gel jar upper end is provided with main valve; Main silica gel jar lower end links to each other with respirator; The pipeline of secondary silica gel jar upper end is provided with auxiliary-valve, and secondary silica gel jar lower end is connected with respirator, and main valve is connected with transformer with the pipeline of auxiliary-valve upper end.
