Anhui Mingge Electric Co., Ltd.

The trinity of high-voltage switchgear, transformers and low-voltage switchgear is highly complete;
High and low voltage protection is complete, operation is safe and reliable, and maintenance is simple;
It occupies less space, saves investment, has a short production cycle and is easy to move;
Wiring solutions are flexible and diverse;
Unique structure: The unique honeycomb structure double-layer (composite plate) shell is strong, insulated, heat dissipated, ventilated, beautiful, and has high protection level. The shell materials are stainless steel alloy, aluminum alloy, cold-rolled plate, and color steel plate;
Various types: general type, villa type, compact type, etc.;
The high-voltage ring main unit can be equipped with a network automation terminal (FTU) to achieve reliable detection of short circuits and single-phase ground faults. It has the \"four remote\" function to facilitate distribution network automation upgrades.

transformer
The intelligent integrated substation uses low-loss, oil-immersed, fully sealed S9, S10, and S11 series transformers. It can also choose resin-insulated or NOMEX paper-insulated environmentally friendly dry-type transformers. The bottom can be equipped with a trolley so that the transformer can be easily accessed.

High voltage side
The high voltage of intelligent integrated substations is generally protected by a load switch and a fuse combination. After one phase of the fuse is blown, the three-phase linkage trip occurs. The load switch is available in compressed air, vacuum, sulfur hexafluoride and other types. It can be equipped with an electric operating mechanism to achieve automatic upgrades; the fuse is a high-voltage current-limiting fuse with an impactor, which has reliable action and large breaking capacity. The main technical parameters are shown in the table below.

Low voltage side
The main switch on the low-voltage side adopts a universal or intelligent circuit breaker for selective protection; the outlet switch adopts a new type of plastic case switch, which is small in size and has short arcing, and can reach 30 circuits; the intelligent automatic tracking reactive power compensation device has two switching modes: contactor and non-contact for users to choose.
