Description
Technical field
The utility model relates to transformer station's anti-misoperation apparatus, is specially transformer station's anti-misoperation phonetic warning device.
Background technology
For many years in the electric system because the operation personnel go to the wrong way at interval, and maintainer's mistake climbs charging equipment and the major accident that takes place happens occasionally, the economic loss that causes is also quite big.Along with development in science and technology, various anti-misoperation products arise at the historic moment in recent years.The important factory of electric system, stand and progressively installed and used new anti-misoperation apparatus, as anti-misoperation locking device etc.But each anti-misoperation apparatus be not yet improve intact, key also is the people, as the misoperation fault analysis that takes place from the present whole nation as can be known, the operation personnel go to the wrong way at interval, and the monitoring personnel guard and ineffectively cause mistake to climb, open and close by force the accident that maloperation takes place lock still to take place.Therefore under a stable condition, caution, the prompting strengthened operating personnel are very important.At present, do not see transformer station's anti-misoperation phonetic warning device, do not see the bibliographical information of Related product yet.
Summary of the invention
The utility model provides a kind of transformer station anti-misoperation phonetic warning device in order to solve the problem that does not have transformer station's anti-misoperation phonetic warning device at present.
The utility model is to adopt following technical scheme to realize: transformer station's anti-misoperation phonetic warning device, comprise the control circuit in housing and the housing, be fixed with solar panel on the panel of housing, control circuit comprises the infrared signal process chip, the signal input part of infrared signal process chip is connected with the infrared sensor that is fixed on the case panel through signal amplification circuit, the single-pole double-throw switch (SPDT) of the signal output part of infrared signal process chip on being fixed in case panel with its in segmentation be solidified with the caution voice speech chip link to each other, the signal output part of speech chip links to each other with loudspeaker through power amplification circuit.During use, this attention device is fixed in by the substation equipment, when detecting human body signal, infrared sensor can export corresponding signal, this signal is input infrared signal process chip after signal amplification circuit amplification, filtering etc. are handled, the signal output part output control signal opening voice chip of infrared signal process chip, speech chip is exported the caveat tone signal that segmentation is solidified in it, and the caveat tone signal is amplified through power amplification circuit, sends the caution voice by loudspeaker.When substation equipment was in normal operation, single-pole double-throw switch (SPDT) was pulled to a side, and this moment, attention device sent interval of living in title, numbering phonetic warning, in case operating personnel go to the wrong way at interval; During the grid equipment maintenance, single-pole double-throw switch (SPDT) is pulled to opposite side, attention device sends the phonetic warning of " equipment is charged, No climbing ", climbs charging equipment to prevent maintainer's mistake.
Transformer station described in the utility model anti-misoperation phonetic warning device, the power-supplying circuit that in its control circuit, also comprises the power amplification circuit between speech chip and the loudspeaker, this power-supplying circuit comprises triode BG2 and triode BG3, the base stage of triode BG2 links to each other with the signal output part of infrared process chip through resistance, the collector of triode BG2 links to each other through the base stage of resistance with triode BG3, the collector of triode BG2 also links to each other and links to each other with power supply with the emitter of triode BG3 through resistance, and the power supply line end of the power amplification circuit between the emitter of triode BG3 and speech chip and the loudspeaker links to each other.Power amplification circuit between speech chip and the loudspeaker is in non-power supply state at ordinary times, when infrared sensor detects human body signal, the infrared signal process chip is exported control signal in the opening voice chip, make the power amplification circuit power supply of power-supplying circuit conducting (even triode BG2, BG3 conducting) between speech chip and loudspeaker.Can reduce the power consumption of attention device like this, increase the ability that conforms.
Transformer station described in the utility model anti-misoperation phonetic warning device adopts infrared detection technique, microelectronics control, voice to solidify and heliotechnics, can cause that operating personnel note with title, the numbering at voice reminder operating personnel interval of living in clearly; When overhauling, electrical network can prevent that the maintainer from going to the wrong way the interval mistake and climbing charging equipment.Its reasonable in design, self-powered (Ni-MH battery group power supply sun power floating charge mode) has characteristics such as power consumption is little, volume is little, cost is low.It is closed that structure adopts, conform and anti-electromagnetic capability strong, filled up the blank of present no like product.This attention device and existing anti-misoperation locking device are used better effects if.
