Description
Technical field
The utility model belongs to power transmission and distribution technical field, relates to a kind of residential area distribution transforming load factor control device.
Background technology
Residential area is due to its characteristic, and the distribution transforming load factor cyclic fluctuation of residential area power distribution room is larger, and daytime on working day, main transformer load factor was low, and loss is high, and noise is large.Particularly newly-built residential area, because occupancy rate is lower, the problems referred to above are more obvious.
Summary of the invention
Technical problem to be solved in the utility model is, provides one can when load factor is low, the residential area distribution transforming load factor control device reduced the wastage.
Residential area distribution transforming load factor control device of the present utility model, comprises 1# distribution transforming and 2# distribution transforming, and high-pressure side and the low-pressure side of described 1# distribution transforming and 2# distribution transforming are respectively arranged with high-voltage switch gear and low tension switch;
It also comprises controller and low voltage liaison net switch, and the high-pressure side of described 1# distribution transforming and 2# distribution transforming is separately installed with current transformer, and two current transformers are connected to the signal input part of controller; Described low voltage liaison net switch is connected between the low-pressure side of 1# distribution transforming and 2# distribution transforming; The delay switch of the high-voltage switch gear of 2# distribution transforming and the delay switch of low voltage liaison net switch is provided with in described controller;
The signal that described controller can transmit according to current transformer, when load factor is low: the delay switch controlling the high-voltage switch gear disconnecting 2# distribution transforming, the delay switch of closed low interconnection switch simultaneously; Now, only powered by 1# distribution transforming.When load factor height, the delay switch of the high-voltage switch gear of timing closing 2# distribution transforming, disconnects the delay switch of low voltage liaison net switch simultaneously, now, is powered by 1# distribution transforming and 2# distribution transforming simultaneously.
Due to when load factor is low, shielding 2# distribution transforming, is only powered by 1# distribution transforming.Thus reduce loss.
Described controller is arranged in 1# distribution transforming, and the power interface of described controller is connected to the low-pressure side of 1# distribution transforming, is directly powered by the low-pressure side of 1# distribution transforming.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model embodiment.
