Abstract
The utility model provides a high-voltage operation reminder which comprises a power supply module, a signal collection module, a programmable logic controller (PLC) module, a program execution module and a voice output module. The power supply module is composed of a self-excited voltage stabilizing circuit; the signal collection module is formed by connecting normally-open contacts of different switches via a flexible copper-core wire with an insulating layer, and timely inputs state signals of the different switches collected in different time to a CPU of a PLC; according to the switch states of the input signals, the PLC module deciphers program logics of a user, and outputs the deciphered logic result to the program execution module via output parts; the program execution module is composed of a single-chip microcomputer, identifies the state signals of the different switches collected in different time, and outputs corresponding voice instructions; and the voice output module which is composed of a signal amplifier amplifies the signals sent from the program execution module, and plays the signals via a loudspeaker. The high-voltage operation reminder can avoid human injury and equipment accidents led by operating the high-voltage switches by mistake, improves the safety of operators in operating the high-voltage switches, and ensures stable operation of equipment.
Description
Technical field
The utility model belongs to electric substation's high voltage protection device, particularly a kind of operation with high pressure reminiscences.
Background technology
In now a lot of hyperbaric chambers, panel box is all to arrange successively, and Pan Xiangding is marked with sequence number, has working position and testing position pilot lamp, has and closes a floodgate and separating brake pilot lamp, also hangs with the indications such as corresponding function board.The electrician of electric substation, carry out and have a power failure or power transmission, while also having a homogeneous example showing an inverse connection between the middle term and the major term lock, often in hand, to hold work card or work ticket removes operating switch to corresponding dish case, under the heartily condition of operator, be that the switch that can come analysis and distinguishing to operate by each position of the switch and conscientious observation signal pilot lamp is to be operated in what state, whether can carry out normal running, then operating, is all single signal lamp indication substantially.But sometimes can because of signal lamp damage or the position of the switch not in place think to stop just directly shake out primary cut-out, or operator's state of mind is not good, absent minded, wrongly 1-2 is regarded as to 2-1 just goes direct on-load to shake out isolating switch.Also have power failure time only disconnected isolating switch, do not disconnect disconnector, what have only disconnects disconnector and does not have cut-off breaker etc. reason to cause irremediable accident.
Through hundreds of electrify gas accident statistics and the analyses of causes are drawn, because maloperation causes 75% the ratio of occupying of accident.
A minute isolating switch, minute earthing are just just pointed out handcart in voice message when experiment position is shifted working position onto in mistake, experimental results show that it is worthless, because isolating switch is in testing position and while having closed a floodgate, while advancing handcart to working position, belong to and between contact, likely reach arcing distance, can cause the accident, wait and hear that voice message just there's not enough time.
As can be seen here, if operator just sees merely signal lamp or with feeling that operate high pressure switch, operation are very insecure.How strengthening reminding operator can understand all states of switch when operation, is very important according to step operation.
Summary of the invention
The purpose of this utility model is to provide a kind of operation with high pressure reminiscences, can make the operator of electric substation when carrying out high-tension apparatus operation, can not only see the indication of signal lamp, can also hear the prompting of voice, remind operator's high-voltage switch gear links place state, whether can close a floodgate or the operation of separating brake, remind and operate by operation steps, avoid causing the accident because of maloperation.
The purpose of this utility model realizes by following technical proposals:
An operation with high pressure reminiscences, is characterized in that comprising that power module, signal acquisition module, PLC module, program execution module, voice output module five parts form, and is specially:
Power module, is comprised of auto-excitation type mu balanced circuit, with overcurrent, short-circuit protection, alternating current 220V power supply is become to stable direct current 24V, for signal acquisition module, PLC module, execution module, voice output module provide reliable working power;
Signal acquisition module, takes from the normally opened contact of each switch, with the copper core flexible cord of tape insulation layer, connects, and each switch state signal that different time is collected is input in the CPU of PLC in time;
PLC module, according to the on off state of the input signal reading in, understands user program logic, by user logic, draws correct output signal; The result that logic is understood is exported to program execution module by output block;
Program execution module, is comprised of single-chip microcomputer, and each switch state signal that different time is collected is identified, and exports corresponding phonetic order simultaneously;
Voice output module, by signal amplifier installation composition, the signal that program execution module is sent here amplifies, and by loudspeaker, plays.
Compared with prior art, stop operator and just seen merely signal lamp or the danger of just removing operate high pressure switch with sensation.Avoided the personal injury and the equipment breakdown that because of maloperation high-voltage switch gear, cause, the security while having improved operator's operate high pressure switch, has guaranteed the stable operation of equipment.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, 2, a kind of operation with high pressure reminiscences, is characterized in that comprising that power module, signal acquisition module, PLC module, program execution module, voice output module five parts form, and is specially:
(1) reminiscences power module.By auto-excitation type mu balanced circuit, formed, with overcurrent, short-circuit protection, alternating current 220V power supply is become to stable direct current 24v, for signal acquisition module, PLC module, execution module, voice output module provide reliable working power.Use the copper core flexible cord with insulation course to connect;
(2) signal acquisition module, takes from the normally opened contact of each switch, comprises the input signal 1 of reminiscences, takes from isolating switch co-bit; Input signal 2, takes from isolating switch minute position; Signal 3, takes from testing position; Signal 4, takes from working position; Signal 5, takes from earthing co-bit; Signal 6 is taken from earthing minute position; Signal 7 is taken from electrification in high voltage; Signal 8 is taken from locking; Signal 9 is taken from release; Signal 10 is taken from energy storage; Signal 11 is taken from not energy storage; Signal 12 is taken from separating brake switch; Signal 13 is taken from combined floodgate switch; Signal 14 is taken from switch zero-bit.SB is enabling signal,
With the copper core flexible cord of tape insulation layer, connect, each switch state signal that different time is collected is input in the CPU of PLC in time;
(3) PLC module, according to the state of the input signal reading in, understands user program logic, by user logic, draws correct output signal; The result that logic is understood is exported to program execution department by output block and is divided;
