Abstract
The utility model provides an on-site prompting device for substation remote operation, which is composed of a DC power supply, a prompting loudspeaker, a prompting lamp, an intermediate relay and a measurement control device output contact, wherein the measurement control device output contact and the coil of the intermediate relay are serially connected and then parallelly connected between the positive electrode and the negative electrode of the DC power supply; one pair of contacts of the intermediate relay are parallelly connected onto two ends of the measurement control device output contact to serve as self lock; and the other pair of contacts of the intermediate relay are serially connected with the prompting loudspeaker and the prompting lamp in parallel connection and then parallelly connected between the positive electrode and the negative electrode of the DC power supply. Compared with the prior art, a measurement control device in a comprehensive automation system of the substation drives in advance the loudspeaker equipment and presses a button switch at a fixed time or in advance, a remote prompting command is sent and triggered, operation is carried out again after on-site workers are prompted to leave, and the purpose of prompting the on-site persons can be achieved.
Description
Technical field
The utility model relates to a kind of warning device, the on-the-spot suggestion device of especially a kind of transformer station remote operation.
Background technology
In " State Grid Corporation of China's electric power safety working regulation revision supplementary provisions ", explicitly call for: before remote operation primary equipment, should send cue to scene, remind Field Force away from operating equipment.In real work, also there is the generation of the situation such as power scheduling control centre remote operation switch or the AVC of main website self-regulation capacitor switch when Field Force works.Have at the scene in staff's situation, easily impact and interference site operation personnel carry out work to remote operation primary equipment on the one hand; The transforming plant primary equipment probability that especially breaks down when drop-out current in operating process is high a lot of than usual on the other hand, and in the time breaking down easily to Field Force cause serious injury especially indoor 35kV and a following breaker apparatus more serious to personnel's injury.But, the on-the-spot suggestion device of transformer station's remote operation that currently available technology does not also drive by measure and control device in master-control room.Therefore, designing the on-the-spot suggestion device of a kind of transformer station's remote operation driving by measure and control device in master-control room, is the current technical issues that need to address.
Summary of the invention
Technical problem to be solved in the utility model is to provide the on-the-spot suggestion device of a kind of transformer station's remote operation driving by measure and control device in master-control room.
The technical scheme in the invention for solving the technical problem is:
The on-the-spot suggestion device of transformer station's remote operation, outputing contact by DC power supply, Tip Sound, prompting light, auxiliary relay and measure and control device forms, the coil that measure and control device is outputed contact and auxiliary relay is connected in parallel between the both positive and negative polarity of DC power supply after connecting, the wherein pair of contact of auxiliary relay is connected in parallel on measure and control device outputs the two ends of contact, as self-locking, the another pair of contact of auxiliary relay is connected in parallel between the both positive and negative polarity of DC power supply after connecting with Tip Sound in parallel and prompting light.
Select scheme as one of the present utility model, described measure and control device is outputed contact and is connected in parallel on the two ends of the AVC of main website self-regulation capacitor switch, scheduling station issues remote operation instruction by 104,101 stipulations and passes to transformer station's telemechanical machine by data dispatching net, pass to transformer station measurement and control device by transformer station's telemechanical machine by network in transformer station again, finally output contact action by transformer station measurement and control device by the measure and control device of the on-the-spot suggestion device of drive circuit instruction transformer station remote operation.
Select scheme as one of the present utility model, it is push-button switch that described measure and control device is outputed contact, push-button switch is arranged on scheduling station, Tip Sound, prompting light are located at transformer station's remote operation scene, before AVC remote control capacitor switch, first press the button switch, send and trigger remote prompting order.
The principle of this invention is that first power scheduling control centre drives long-range prompt command in main website before straighforward operation primary equipment in the distance, drive order to be handed down to the telemechanical machine in transformer station long-range prompting by network channels such as power dispatch data network, drive again the measure and control device in transformer station by telemechanical machine through transformer station's network, finally through the triggering of outputing contact and realize the on-the-spot cue of remote operation of measure and control device.
Compared with prior art, drive in advance stereo set and keep the set time or press the button in advance switch by the measure and control device of complex automatic system in transformer station, sending and trigger remote prompting order.After reminding field personnel to withdraw, then operate; Reach the object of reminding Field Force.
