Abstract
An electromagnet controller for the ascending protector of elevator is composed of magnetic exciter, DC maintaining circuit, constant-current charger, demagnetizing and spark-extinguishing circuit and electromagnetic coil as load. It can make it possible that the braking electromagnet is used as the brake is ascending protector.
Description
Technical field
The present invention relates to a kind of brake electromagnet, specifically a kind of electromagnet controller of elevator up-line protector.
Background technology
Along with constantly the building up and using of flickering high buildings and large mansions, the use amount of elevator is also increasing thereupon, the also corresponding increase of the operational failure of elevator.The control of motor and brake out of controlly when wherein a kind of fault is exactly ascending for elevator causes elevator to rush to summit, thereby causes serious safety misadventure.So national departments concerned has explicitly called in elevator control gear must install elevator up-line protector additional.Core in the elevator up-line protector is exactly the drg that the steel rope in the rapid movement is carried out forced brake.To the performance requriements of drg, the one, it is fast that retro-speed is wanted, to play due protective effect; The 2nd, it is big that lock torque is wanted, can implement the actv. braking; The 3rd, after the braking, if in case have a power failure, drg still need be kept braking mode more than 72 hours, comes to check accident causation and keeps in repair to treat the specialized maintenance personnel.Employed in elevator up-line protector at present, as to satisfy above-mentioned condition drg, its complex structure, with high costs, and can only dependence on import.Thereby concerning the production and applying unit of elevator, the use of elevator up-line protector has increased very big expenditure with regard to corresponding.
Once the someone attempts to adopt the brake electromagnet of cheap, simple in structure and technology maturation as the drg in the elevator up-line protector before this.But; because used controller is not generally established the remanent magnetism circuit on the common brake electromagnet; this just makes electromagnet can't eliminate fast at a large amount of remanent magnetism that glancing impact exists, and causes the shutoff of drg longer delay time, can not satisfy the time needs of elevator up-line protector.And if the mode that adopts forced cut-out to remove remanent magnetism in controller will produce stronger electro spark at the electromagnet glancing impact thereupon, thereby the service life of contact is turn-offed in influence, and then influences the functional reliability of brake electromagnet.The existence of these unfavorable factors has limited the application of brake electromagnet in elevator up-line protector.
Summary of the invention
Purpose of the present invention just provides a kind of electromagnet controller of elevator up-line protector, to overcome above-mentioned unfavorable factor, makes brake electromagnet satisfy the special requirement of elevator up-line protector, and then is fitted in the elevator up-line protector.
The object of the present invention is achieved like this: this controller includes energizing circuit, direct current holding circuit, trickle charging circuit and removes remanent magnetism and arc-suppression circuit, the output of energizing circuit and direct current holding circuit is tapped into load magnet coil L, trickle charging circuit and remove remanent magnetism and arc-suppression circuit is connected between direct current holding circuit and the load magnet coil L.
In controller of the present invention, energizing circuit and direct current holding circuit are two conventional parts in the electromagnet controller, in order to realize the job requirement of electromagnet " big current start, low voltage are kept ".Trickle charging circuit is that the storage battery as backup power is carried out slowly lasting charging; when having a power failure, making storage battery that the vdc that satisfies the abundance of keeping the electromagnetic actuation state can be provided, thereby satisfy the requirement that elevator up-line protector has a power failure and still can reliably brake in 72 hours after braking.Removing remanent magnetism and arc-suppression circuit is by the hypervelocity breakdown switch that disposes in the elevator up-line protector; when it disconnects because of elevator overspeed is up; the magnet coil loop quick by this circuit, that no spark ground disconnects electromagnet; eliminate the remanent magnetism in the magnet coil thus rapidly, realize the snap catch of electromagnet.
By the electromagnet of controller of the present invention control, through severe test repeatedly, thereby, 0.25 second or more dropped to 0.05 second below, satisfied elevator up-line protector desired 0.1 second braking time requirement by original shutoff delay time of electromagnet.And the lock torque of electromagnet and brake structure mode also can satisfy the performance requriements of elevator up-line protector to drg fully.In controller,, can make storage battery keep the electric dormant state of foot for a long time with addition of storage battery and to the trickle charge of storage battery.Therefore; utilize controller of the present invention can satisfy the every electricity function index of brake electromagnet in elevator up-line protector and action index request; thereby can realize brake electromagnet, thereby make brake electromagnet become possibility as the drg in the elevator up-line protector in the elevator up-line protector Application for Field.Can guarantee under the elevator safety performance demands that like this technology that reduces elevator up-line protector greatly constitutes, cost and price, thereby meets the need of market.

According to the different operating needs of elevator service personnel, controller of the present invention can provide following three kinds of different excitation Starting mode:
First kind is to exchange 220 volts of electrifying startups.This is normal Starting mode.At first make hypervelocity breakdown switch K closure, connect the lead-in wire of storage battery E then, connect alternating current 220V voltage again and get final product start-up circuit.
Second kind is to start with hypervelocity breakdown switch K.When hypervelocity breakdown switch K is in off-state, connects storage battery E, and then connect the alternating current 220V power supply.This moment is because hypervelocity breakdown switch K is in off-state, relay J
1Do not work, so control circuit does not start, breakdown switch K gets final product start-up circuit as long as closure exceeds the speed limit.
The third is to start with storage battery E.Hypervelocity breakdown switch K is in off-state, connects the alternating current 220V power supply, connects storage battery E then and gets final product start-up circuit.
The two kinds of Starting mode in back are to use under the occasion of special requirement, generally do not advise adopting.
Controller of the present invention is with the action command of hypervelocity breakdown switch K as the electromagnet braking; With hypervelocity breakdown switch K serial connection relay coil J
