Overview
Jiuchuang Transformer Maintenance free Intelligent Respirator is an air dehumidification and purification device used for oil immersed transformers, transformers, on load tap changers, or other electrical equipment with insulating liquids. The maintenance free respirator for transformers is installed on the air inlet of the transformer oil storage tank.
Product Details
Product Introduction
JiuchuangTransformer maintenance free intelligent respiratorIt is an air dehumidification and purification device used for oil immersed transformers, transformers, on load tap changers, or other electrical equipment with insulating liquids. The maintenance free respirator of the transformer is installed on the inlet of the transformer oil storage tank. When the oil volume of the transformer or transformer expands or contracts due to changes in oil temperature during operation, it forces the gas inside the oil storage tank to breathe through the dehumidifier. The air enters the transformer through the filter at the bottom of the dehumidifier and the glass tank filled with silicone, ensuring that the inhaled gas is dry (moisture is adsorbed by the desiccant) and clean (dust and impurities are blocked by the filter), in order to maintain the cleanliness and insulation strength of the transformer oil.
Product Features
(1)Oil cup design: compatible with traditional respiratory habits, it can clearly indicate the current breathing status of the transformer.
(2) Auxiliary heating: When the ambient temperature is low, activate auxiliary heating to prevent condensation or freezing of the bottom filtering device; At the same time, it also prevents the oil in the oil cup from freezing at low temperatures.
(3)Condensed water discharge: During regeneration heating, ensure that the condensed water on the glass wall is quickly discharged.
(4)Desiccant powdering treatment: The equipment is in a long-term shaking state and the desiccant is regenerated and heated, which leads to the powdering of the desiccant. This equipment optimizes the structure to ensure that the powdered desiccant does not block the air inlet.
(5)Heating device fault diagnosis: By monitoring the heating power, the reliability of the heating device can be determined.
(6)Respiratory volume monitoring: detect the respiratory volume of one cycle and determine whether the connecting pipe is leaking; Establish a corresponding relationship between transformer oil temperature, breathing volume, and breathing rate.
Product advantages
Product features
(1)Installed on the air inlet of the oil storage tank, it prevents humid air from directly entering through drying and absorptionTransformer, to maintain good electrical performance of transformer insulation oil.
(2)The dryer can be heated and regenerated for use. Water vapor passes through the metal mesh and condenses on the glass cylinder, and water droplets flow out of the moisture absorber along the glass cylinder. Drying agent heating regeneration can be achieved in two ways: at predetermined time intervals, when the humidity reaches 40%.
(3)When a malfunction occurs, on-site and remote sound and light alarms can be implemented, and the status of the respirator can be remotely monitored through RS485.
