Vacuum system of UHV Transformer

　　Application:

　　The vacuum devices used in substation industry, power supply bureau, power plant and transformer factory are used for vacuumizing. Vacuum and refill SF6 gas for circuit breaker, transformer, GIS and other electrical equipment. The equipment is a vacuum pumping system composed of vacuum pump as the front stage pump and roots pump as the main pump. The automatic startup and shutdown of roots pump is realized by vacuum relay or electric contact vacuum meter. The unit has the advantages of fast start-up, large air extraction, automatic operation, unmanned operation and operation status displayed by indicator light. This machine has the characteristics of humanized design, low noise, low operating cost and energy saving.

　　Product features:

　　1. Special two-stage vacuum pump and special roots pump are used. The pumping speed and residual pressure index are obviously better than those of the common units using slide valve pump, water ring pump, oil ring pump and X-type vacuum pump (single stage).

　　2. The limit vacuum and working vacuum are higher than other similar products.

　　3. Automatic vacuum relay is adopted, which not only has accurate vacuum value reading, but also has automatic control function.

　　4. Easy to move, flexible to rotate and minimal noise.

　　Technical parameters:

　　Equipment quality requirements, technical standards: strictly in accordance with the national quality standards, technical standards, inspection standards, after passing the factory, the goods provided are brand new and unused. The whole machine is guaranteed for 3 years. During the warranty period, three guarantees will be implemented for major equipment problems. Any abnormal problems will be handled by the supplier free of charge. If it occurs outside the warranty period, the supplier will provide lifelong free technical services and only charge the cost of accessories.

　　Material selection of the whole equipment: the main body of the whole machine is high carbon steel, and the consumables are stainless steel sheet mesh filter materials (which can be cleaned and reused for many times). The main body can choose stainless steel material for oil pipeline according to the user's requirements. Domestic or imported brands can be selected for oil pump and electrical related main components, or explosion-proof is required. Imported filter element or designated brand can be used for filter element.
