Abstract
The invention relates to a mine downhole operation motor emergency circuit. A mine downhole circuit is the lifeline for ensuring mine normal production, and is a major measure of mine safe production, however, a mine tunnel can experience a situation that a circuit problem occurs due to the environment and the current using situation of the mine tunnel, and the safety of workers can be seriously affected once a power failure occurs and equipment such as an elevator stops operation. The mine downhole operation motor emergency circuit comprises a battery pack, the battery pack is connected with a charger and an inverter in series and then is connected to an alternating current contactor, and a KM1 and a KM2 are arranged on the alternating current contactor and are in electric and mechanical interlock. The mine downhole operation motor emergency circuit can continue to supply power to equipment such as a motor in a short time in the situation that power transmission is stopped, and thus precious time for maintenance and evacuation is offered.
Description
Technical field
The present invention relates to a kind of emergency circuit, be specifically related to a kind of down-hole operation motor emergency circuit.
Background technology
The down-hole circuit is the lifeline that guarantees mine normal production, it is also one of major measure of mine safety production, but environment and use present situation due to mine laneway, mine laneway can occur the situation of circuit problem, in case have a power failure, stop as equipment such as elevators, can have a strong impact on the safety of carrying out the staff.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can continue as the down-hole operation motor emergency circuit that motor provides electric power under power-off condition.
The technical solution adopted in the present invention is:
A kind of down-hole operation motor emergency circuit is provided with battery pack in circuit, it is characterized in that:
Incoming transport contactor after described battery pack is connected with charger and inverter.
KM1 on described A.C. contactor, KM2 are the electricapparatus interlocking.
The present invention has the following advantages:
The present invention can be in the situation that electric power carries equipment such as stopping continuing as motor that the electric power of short time is provided, for maintenance with withdraw the time that provides valuable.
Description of drawings
Fig. 1 is circuit diagram of the present invention.
Embodiment
The present invention will be described in detail below in conjunction with embodiment.
A kind of down-hole operation motor emergency circuit of the present invention is provided with battery pack in circuit, incoming transport contactor after battery pack is connected with charger and inverter.KM1 on A.C. contactor, KM2 are the electricapparatus interlocking.When AC power was normal, charger carried out floating charge to battery pack, and KM1 is closed simultaneously, Alternating Current Power Supply bypass output, and inverter is in the hot standby starting state for the treatment of; In AC power when outage,, the KM2 contactor disconnects, and the charger KM2 closure that quits work is uninterrupted for guaranteeing the external control power supply.Inverter starts automatically, the electric energy of battery pack is discharged the normal operation of keeping motor device, and battery pack provides a galvanic current to press to inverter; When AC power was recovered, charger began the battery pack boost charge, and at this moment power up to normal operating condition, is waited for next time and used.
Claims (2)
