Functions and features
1. High voltage switchgear, transformer and low-voltage switchgear have three positions, with strong completeness:
2. Complete high and low voltage protection, safe and reliable operation, and simple maintenance;
3. Less land occupation, less investment, short production cycle and convenient movement:
4. Flexible and diverse wiring schemes;
5. With unique structure and unique honeycomb structure, the double-layer (composite plate) shell is firm, heat insulation, heat dissipation and ventilation, beautiful, and high protection level. The shell materials include stainless steel titanium alloy, aluminum alloy, cold rolled plate, and color steel plate;
6. Diversified universal type, villa type, compact type, etc;
7. The high-voltage ring network cabinet can be equipped with network automation terminal (FTu) to realize reliable detection of short circuit and single-phase ground fault, and has the "four remote" function to facilitate the upgrading of distribution network automation.
It is widely used in urban power grid transformation, residential quarters, high-rise buildings, industrial and mining, hotels, shopping malls, airports, railways, oil fields, wharfs, expressways, temporary power facilities and other indoor and outdoor places.
Normal service conditions
l. The altitude shall not exceed 1000m;
2. Ambient temperature - 25 ℃~+40 ℃:
3. The daily average value of relative humidity is not more than 95%, and the monthly average value is not more than 90%;
4. Installation site: the site without fire, explosion, conductive dust, chemical corrosive gas and severe vibration. If the above conditions are exceeded, the user can negotiate with our company.
High voltage side
High voltage of high/low voltage prefabricated substations is generally protected by load switch fuse combination. After one phase of the fuse is fused, three-phase linkage tripping is performed. The load switch is available in compressed air, vacuum, sulfur hexafluoride and other types, and can be equipped with electric operating mechanism to achieve automatic upgrading. The fuse is a high-voltage current limiting fuse with an impactor, which has reliable action and large breaking capacity. See the following table for main technical parameters. For transformers above 800kVA, zNl2, zN28, Vsl and other vacuum circuit breakers can be selected for protection.
Low voltage side
The main switch at low-voltage side adopts universal or intelligent circuit breaker for selective protection; The outgoing switch adopts a new molded case switch with small volume, short flashover and up to 30 circuits: intelligent automatic tracking reactive power compensation device, with two switching modes of contactor and contactless for users to choose.
Low loss, oil immersed, fully sealed s9, s10, s11 series transformers can be selected for high/low voltage prefabricated substations, and resin insulated or NOMEX paper insulated environment-friendly dry-type transformers can also be selected. Trolleys are equipped at the bottom to facilitate the access of transformers.
