Tsr-12 New Type Environmentally Friendly Fully Insulated Solid Insulated Rmu Ring Main Unit Ring Network Cabinet

Summary:

According to the document spirit of State Grid and the development trend of distribution equipment at home and abroad, Yueqing Liyond Electric Co., Ltd  immediately established a research and development team to develop solid insulated ring main unit. Through two years of unremitting efforts, the company successfully completed the development of TSR-12 (I) series products in the second half of 2012, and passed the type test of the whole project; meanwhile, the company In order to more widely adapt to the different needs of this large market in China, the development of TSR-12 (II) series products and the type test of the whole project were completed in 2014. So as to lay a leading and leading position in the field of solid insulation industry.

Environmental Conditions:

2.1 Ambient air temperature

a) Upper +40ºC;

b) Lower -25ºC.

2.2 Ambient temperature

a) Daily average relative humidity:≤95%;

b) Monthly average relative humidity:≤90%;

c) Daily average saturated vapor pressure:≤2.2kPa,

d) Monthly average saturated vapor pressure:≤1.8kPa.

2.3 Altitude

No more than1500m.

2.4 Operation place

No flammable, explosive hazard, chemical corrosion and severe vibration.

Characteristics:

The TSR-12 ,I and II series products developed by Liyond Electric Co., Ltd  are secondary distribution equipment of 12kV system. The main circuit uses solid insulation as the main insulation structure. The conductive parts are all sealed in the insulation cavity, and the vacuum arc extinguishing chamber is used. It is a breaking element. The scheme includes circuit breaker cabinet, load switch cabinet, load switch + fuse combination electrical cabinet, PT cabinet and metering cabinet, etc. Series products have the following common characteristics:

1.The disconnector and the earthing switch are completely independent and have the ability of quick opening and closing 

2.Three-phase independent poles to completely avoid short circuit between phases 

3.Upper isolation, upper grounding, lower isolation, lower grounding, complete solution 

4.Standard cable external cone head is used for incoming and outgoing lines 

5.The main bus adopts solid insulated bus
