Oil conservator moisture absorber with convenient silica gel replacement

Abstract

The invention relates to an oil conservator moisture absorber with convenient silica gel replacement, which comprises tank bodies communicated with an oil conservator capsule, wherein the tank bodies are filled with silica gel. The oil conservator moisture absorber is characterized in that the number of the tank bodies is at least two, the tank opening of each tank body is provided with a vacuum valve, and the vacuum valves are connected with connecting pipes communicated with the oil conservator capsule through multi-pass pipes. On the premise of ensuring the respiratory capacity of the moisture absorber, the prior moisture absorber with one tank is changed into a moisture absorber with at least two tanks, each single moisture absorber has smaller volume and lighter weight, and the oil conservator moisture absorber can be carried manually to replace the silica gel by one person, is convenient and quick, and saves certain time and maintenance cost, and simultaneously, when the silica gel is affected with damp, the oil conservator is ensured to be in a normal respiratory state during the whole replacement.

Description

technical field [0001] The invention relates to a moisture absorber, in particular to a moisture absorber used for oil storage cabinets of power transmission and transformation equipment such as oil-immersed transformers and reactors. Background technique [0002] The dehumidifier used in the early transformer oil conservator was a single-tank structure. The inner cavity of the capsule of the oil conservator communicated with the atmosphere through the dehumidifier. Oil tank capsules. [0003] Since the size of the moisture absorber is determined according to the volume of the oil conservator (that is, the breathing capacity), the required moisture absorber will be very large on high-voltage and large-capacity power transmission and transformation equipment, such as figure 1 The dehumidifier with a single tank structure has a length of 1 meter and a weight of nearly 35 kg, which is difficult to carry and replace. The silica gel in the tank of the dehumidifier becomes disco...

Problems solved by technology

[0003] Since the size of the moisture absorber is determined according to the volume of the oil conservator (that is, the breathing capacity), the required moisture absorber will be very large on high-voltage and large-capacity power transmission and transformation equipment, such as figure 1 The dehumidifier with a single-tank structure has a length of 1 meter and a weight of nearly 35 kg, which is difficult to carry and replace

The silica gel in the tank of the dehumidifier becomes discolored due to moisture, and the dehumidifier loses its function of filtering moisture in the air. At this time, it is necessary to replace the silica gel in the tank. However, due to the long size and heavy weight of the dehumidifier itself, manual The operation is difficult, and some lifting equipment is required, which will delay a certain amount of time

At the same time, during the replacement process, if the valve connected to the oil conservator above the dehumidifier is closed, it is equivalent to cutting off the passage between the capsule in the oil conservator and the atmosphere. It is a hidden danger for the transformer

If the valve is opened for replacement, a small amount of moist air and dust will enter the capsule of the oil conservator through the joint pipe, which will increase the weight of the bottom of the capsule, easily cause false oil level phenomenon on the oil gauge, and cause misjudgment of operation monitoring
