Abstract
The invention provides a kind of method of coal mine underground electric locomotive trolley line sectional power supply.When locomotive driving arrived certain section air wire, switch gave for this section air wire automatically; After locomotive sailed out of, switch made this section air wire dead electricity, and air wire is in electroless state at ordinary times like this, had guaranteed that air wire is walked down and staff's safety.In addition, automatic switch is provided with earth leakage protective, and outage latch-up protection circuit makes automatic switch not only have the function of auto-power-cutting, and the electric shock accidents that caused of the electricity that can actv. prevents to misdeliver.
Description
The present invention belongs to a kind of method of supplying power to, particularly to a kind of method of coal mine underground electric locomotive trolley line sectional power supply.
The air wire that present China's coal-mine down-hole is used generally adopts the subregion insulation, promptly utilizes zoning switch to carry out electric connection.The effect of zoning switch is maintenance or has a power failure when working below air wire.The whole dead electricity of this switch air wire backward during power failure.Otherwise air wire is charged for a long time.
There are indivedual mines to fix a point to cut off the power supply now at shaft station installing travel switch.Tangshan Mine Kailuan Mining Administration's design-calculated " servant forfeits electric installation with automatic music in the parking lot on the roadway " as publishing on " safety of coal mines " 85 years the 7th phases promptly belongs to this example.And " electric locomotive parking area auto-power-cutting switch " that yangquan coal mine Electronic Equipment Factory produces also only is used for the parking lot.And other air wires are still charged for a long time.Make under the line walking and staff cause Danger Electric shock risk.
The method that the purpose of this invention is to provide a kind of coal mine underground electric locomotive trolley line sectional power supply.Behind the air wire sectional power supply, when locomotive driving arrived certain section air wire, switch gave for this section air wire automatically.To guarantee the needs of locomotive driving.After locomotive sailed out of, switch made this section air wire dead electricity.Air wire is in electroless state at ordinary times like this.Guaranteed the safety of workmen under pedestrian and the line.Automatic switch also is provided with earth leakage protective in addition, widely different road is checked in outage.Make automatic switch not only have the function of auto-power-cutting, and the electric shock accidents that caused of the electricity that can actv. prevents to misdeliver.
Solution of the present invention is that electric vehicle overheading line is carried out segmentation according to actual conditions, utilizes cable that the traction substation direct supply is drawn then.
Further solution of the present invention is that automatic switch of installing is to realize the conversion of signal on every section air wire, and the direct supply on the cable is delivered on every section air wire by automatic switch.When locomotive operation arrives certain section air wire, the locomotive electrical motor transfers generating state to by motoring condition, to air wire feedback one direct current voltage, this voltage is greater than voltage detecting loop threshold voltage, this loop works state changes, when air wire ground insulation during greater than 11K Ω, it is constant that insulation detects the loop running state, at this moment the starting circuit state changes, the oscillator starting of oscillation, trigger circuit output trigging pulse is extremely gone up to the control of one-way SCR, the silicon control conducting, and the direct supply on the cable is delivered on this section air wire.After locomotive sails out of this section, the air wire dead electricity.
