Moisture absorbent replacement-free breather provided with wireless remotely-controlled main transformer and control method

Abstract

The invention relates to a moisture absorbent replacement-free breather provided with a wireless remotely-controlled main transformer and a control method. The breather comprises a silica gel tank three-way tube and a hot-air blower three-way tube, wherein a main tube of the silica gel tank three-way tube is connected with a main transformer breathing tube, a branch tube is provided with an electromagnetic valve A which is connected with a silica gel tank A, and another branch tube is provided with an electromagnetic valve B and is connected with a silica gel tank B; the silica gel tank A and the silica gel tank B are filled with allochroic silica gel serving as a hygroscopic material; a main tube of the hot-air blower three-way tube is connected with a hot-air blower, a branch tube is provided with an electromagnetic valve C which is connected with the silica gel tank A, and another branch tube is provided with an electromagnetic valve D and is connected with the silica gel tank B; the opening and closing of the electromagnetic valves and the hot-air blower are controlled remotely in a wireless way through a remote control signal transmitter. By adopting the breather, major unsafe factors are avoided, and safe running of the main transformer is ensured effectively. Meanwhile, waste of manpower and material resources and environmental pollution caused in the replacing process of a moisture absorbent are avoided.

Description

technical field [0001] The invention relates to a respirator with a wireless remote control main transformer without replacement of a hygroscopic agent and a control method. Background technique [0002] When the main transformer is in operation, it will breathe with the outside air through the breathing tube. If there is no respirator installed on the breathing tube, the main transformer will directly inhale the humid air from the outside. Especially in rainy and humid weather, the main transformer is more likely to be damp. When the traditional main transformer respirator’s moisture-absorbing filler changes color and is saturated with moisture, the staff needs to carry a qualified dry hygroscopic agent or a silicone tank filled with a qualified hygroscopic agent to the main transformer site for electrified replacement. During the replacement process, the main transformer breathing tube is in contact with the outside world. Direct communication with the atmosphere will caus...

Problems solved by technology

[0005] The present invention makes improvements to the problems existing in the above-mentioned prior art, that is, the technical problem to be solved by the present invention is to provide a respirator with a wireless remote control main transformer without changing the hygroscopic agent and a control method, without the need for staff to go to the main transformer The work of replacing the hygroscopic agent with electricity on site solves the problem that the traditional main transformer respirator needs to withdraw from the heavy tile protection when replacing the hygroscopic agent and has potential safety hazards, and overcomes the problem that the main transformer breathing tube is directly connected to the outside atmosphere when the silicone tank is removed The breathing airflow of the main transformer can directly inhale the external moisture and cause the defects of dampness, thus effectively ensuring the safe operation of the main transformer, and also avoiding the waste of manpower and material resources and environmental pollution in the process of replacing the hygroscopic agent. Compared with the traditional main transformer respirator has a huge advantage over
