Description

Transformer respirator silicone and oil level online monitoring alarm

technical field

The utility model relates to the technical field of a transformer respirator, in particular to a transformer respirator silica gel and an oil level on-line monitoring alarm.

Background technique

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 cause changes in the breathing airflow of the main transformer, which may lead to serious failures of the main transformer gas relay heavy tile malfunction. Therefore, the traditional main transformer respirator must withdraw the main transformer heavy tile protection device when replacing the adsorbent. The withdrawal time is as long as 4 to 5 hours.

Another disadvantage of the traditional main transformer respirator is that when replacing the color-changing silica gel, after the silicone tank is removed, the breathing airflow of the main transformer is directly communicated with the outside atmosphere, making it easy for moisture and water to invade the main transformer oil through the breathing tube of the main transformer. And changing the hygroscopic agent will cause waste and also easily pollute the environment.

In the prior art, such as a transformer respirator disclosed in CN201310029094.0 and a new type of main transformer respirator disclosed in CN201520462444.7, its shortcoming is that it depends entirely on the operator to find the equipment within the pre-arranged inspection period. Faults and defects, due to the weather, sometimes the color-changing silica gel in the respirator will change color in advance, and the operator cannot detect it early, causing environmental pollution and equipment failure, and then causing power outages and economic losses. If the transformer is abnormal or the silica gel is not replaced in time, the color of the silica gel will turn pink. If the transformer continues to operate for a long time, it will cause permanent damage to the transformer winding. The above devices cannot monitor the oil level. If the transformer is short of oil, the oil level indicator will become colorless. If the transformer continues to operate, the transformer will burn out; if the transformer winding runs abnormally, the transformer oil will become darker or black. , will cause damage to the transformer.

Utility model content

In view of this, the purpose of this utility model is to provide a transformer respirator silica gel and oil level online monitoring alarm for the deficiencies in the prior art. Whether the color of the oil is normal, if the color is abnormal, an abnormal message will be sent to the background, which can accurately judge whether the color-changing silicone and oil are normal, and the heavy tile protection device does not need to be withdrawn.

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

A transformer respirator silica gel and oil level on-line monitoring alarm, including a tank containing silica gel particles and a conduit communicating with the tank, the conduit is connected to the breathing tube of the oil tank, and the conduit is provided with a solenoid valve. The oil level pipe on one side of the fuel tank is provided with an oil level color sensor through a bracket, and a silicone color sensor is provided on one side of the tank body. The solenoid valve, oil level color sensor and silicone color sensor are all connected with the programmable controller. connected, the programmable controller is connected with a wireless communication module.

The tank body communicates with the conduit through a quick connector.

The air outlet pipe on the tank body is provided with a rainproof cover.

The rainproof cover is an inverted U-shaped structure.

The air outlet of the rainproof cover is trumpet-shaped.

The air outlet of the rainproof cover is provided with a sponge, and the air outlet of the rainproof cover is provided with a bar to prevent the sponge from being blown out.

The air outlet of the tank body and the lower branch pipe are all provided with a filter screen, and the aperture of the filter screen is smaller than the diameter of the silica gel particles.

Beneficial effects of the present utility model: the oil level color sensor and the silica gel color sensor of the present utility model both adopt TCS230 color sensor, there are 64 photodiodes in the sensor, 16 photodiodes are equipped with red filters, and 16 photodiodes are equipped with Green filter, 16 photodiodes with blue filter, and the remaining 16 without any filter, which can pass through all light information. When working, the required filter can be dynamically selected through two programming pins When a color filter is selected, it only allows a specific primary color to pass through and prevents other primary colors from passing through; when the incident light is projected on the TCS230, different combinations of photodiode control pins can be selected. The filter then passes through the current-to-frequency converter to output square waves of different frequencies, and different colors and light intensities correspond to square waves of different frequencies. Then according to the principle of light mixing (that is, any light is composed of three colors of red, green and blue), to identify the different colors emitted by the projected light. There are LED lights on the tank and the oil level tube, and the sound and light controller is used to control the LED work. The LED lights are aimed at the silica gel to increase the light and illuminate at night. The projected light passes through the silica gel and is reflected to the surface of the color sensor, and the color sensor outputs For different RGB three primary colors, when the silicone color is normal, the frequency value output by the color sensor is stored in the programmable controller. If the silicone fails to cause a color change, the programmable controller will compare the difference between the new color and the stored color. Make normal or abnormal judgments. If the color of the silica gel is abnormal, the GSM module is used to notify the operator. When the oil in the fuel tank turns black, the oil level color sensor on the oil level tube detects that the oil level tube is black, and the programmable controller compares the received color with the stored color (black), and the wireless communication module notifies Backstage.
