The shortcomings that formula is：1st, wiring is complicated, safeguards, maintenance inconvenience；2nd, need to increase by 2 electric wires in illuminalive power-supply loop；3rd, voltage damages
Mistake is one times of the general single control mode of connection, and during using copper core 2.5mm2 electric wires, power supply distance is no more than 100m, using copper core
During 4mm2 electric wires, power supply distance is no more than 150m.
Utility model content
Technical assignment of the present utility model is to be directed to above the deficiencies in the prior art, and provides a kind of power plant transporting coal trestle
Arrangement.
Technical scheme is used by the utility model solves its technical problem：A kind of power plant transporting coal trestle arrangement knot
Structure, including coal yard, coal crusher house, main building transporting coal transfer station, and the light distribution box in the coal crusher house, wherein
Unipolar alternate current contactor is provided with the current supply circuit of the light distribution box, in the light distribution box, coal yard and main building
Dual control single-pole switch is equipped with transporting coal transfer station, the dual control single-pole switch passes through a control electricity with unipolar alternate current contactor
Cable connects.
Further improve：The dual control single-pole switch being arranged on light distribution box is the first dual control single-pole switch, is arranged on
Coal yard is the second dual control single-pole switch with the dual control single-pole switch on main building transporting coal transfer station.
Further improve：The coal crusher house includes three layers of one layer of coal breaker and coal breaker, and loop is first after coal yard extraction
Into three layers of coal breaker, one layer of coal breaker is then entered back into, is finally entering main building transporting coal transfer station.
Further improve：The light distribution box is located at three layers of coal breaker, and the light distribution box is located at three layers of coal breaker
Loop in.
The advantages of the utility model：1st, wiring is simple, safeguards, overhauls conveniently；2nd, operations staff is facilitated to operate；3rd, electricity is reduced
Crushing loses, and increases power supply distance, using copper core 2.5mm2During electric wire, power supply distance is up to 200m, using copper core 4mm2During electric wire,
Power supply distance is up to 300m.
