Abstract
The utility model discloses a three-ring transformer alternating current ice melting device which comprises wire inlet cabinets, three-ring AC transformers, a bus coupling cabinet and a feeder cabinet, wherein the wire inlet cabinet I is connected with a 110KV side of the three-ring AC transformer A, the 35 KV side of the three-ring AC transformer A is connected with the wire inlet cabinet II, the wire inlet cabinet is connected with the 35 KV bus coupling cabinet, the 35KV bus coupling cabinet is connected with the wire inlet cabinet III, the wire inlet cabinet III is connected with the 110KV side of the three-ring AC transformer B, the 6KV side of the three-ring AC transformer B is connected with the wire inlet cabinet, the wire inlet cabinet IV is connected with the feeder cabinet, and the feeder cabinet outputs a voltage of 2.205KV. The three-ring transformer alternating current ice melting device provides a paper line short-circuit ice melting voltage; and the ice melting current is regulated through regulating the short-circuit length of a line, and better line ice melting effect is achieved. According to the three-ring transformer alternating current ice melting device, ice is more conveniently and rapidly melted outwards from a transformer substation to outside, all outlet wires can be subjected to ice melting once or in batch, and the cost and the time are saved.
Description
Technical field
The utility model relates to power overhead network deicing device in winter, and particularly three coil transformers exchange deicing device.
Background technology
At present, known power overhead network de-icing technology has DC ice melting, mode ice-melt, the ice-melt of system voltage ac short circuit etc.DC ice melting needs the device that melts of configure dedicated, and investment is big, weak effect, use are inconvenient; The mode ice-melt needs corresponding load and allocates, and receives the supply network restriction; The ice-melt of system voltage ac short circuit needs suitable voltage, suitable overhead transmission line could be realized ice-melt.
By on can know that above-mentioned existing power transmission line deicing device on reality is used, obviously has defective and exists, and remain to be improved.
Thus, the improving of the above-mentioned defective of the utility model thoughts is that the spy concentrates on studies and cooperates repetition test, proposes a kind of reasonable in design and effectively improve the utility model of above-mentioned defective finally.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned shortcoming, provides a kind of three coil transformers to exchange deicing device, guarantees that ice-melt is efficient and convenient, practices thrift cost.
For solving the problems of the technologies described above the technical scheme that the utility model adopts: a kind of three coil transformers exchange deicing device, comprise incoming line cabinet, three circle AC transformers, female cabinet and feeder line cabinet of joining; No. 1 incoming line cabinet connects the 110KV power transmission line; No. 1 incoming line cabinet connects A three circle AC transformer 110KV sides, and A three circle AC transformer 35KV sides connect No. 2 incoming line cabinets, and No. 2 incoming line cabinet connects the female cabinet that joins of 35KV; The female cabinet that joins of 35KV connects No. 3 incoming line cabinets, and No. 3 incoming line cabinet connects B three circle AC transformer 110KV sides; B three circle AC transformers 6 KV sides connect No. 4 incoming line cabinets, and No. 4 incoming line cabinet connects the feeder line cabinet, feeder line cabinet output 2.205KV.
Adopt the concrete operations step of said apparatus ice-melt following:
(1) measures the DC ice-melting impedance;
(2) according to line parameter circuit value measuring and calculating line short circuit point K;
(3 draw back the feeder line cabinet breaker, and outlet is connected to DC ice-melting;
(4) according to debugging feeder line cabinets such as ice melting current, No. 3 incoming line cabinets, No. 4 incoming line cabinet protection setting values;
(5) the female cabinet breaker that joins of 35KV that closes;
(6) the incoming line cabinet circuit breaker that closes No. 3;
(7) the incoming line cabinet circuit breaker that closes No. 4;
(8) the feeder line cabinet feeder line circuit breaker that closes;
(9) can regulate short circuit point K according to the feeder line actual current, make electric current, guarantee the ice-melt effect at zone of reasonableness.
This device can provide suitable line short ice-melt voltage, regulates ice melting current through regulating line short circuit length, makes line ice-melting reach better effect; It is more convenient with such method circuit to be carried out ice-melt, and can be from transformer station to external radiation, and all outlets can disposable or ice-melt in batches, practices thrift cost and time.
