Description

Electrification voice message insulated pull rod device and using method thereof for high-voltage switch gear deciliter disconnecting link
Technical field
The present invention relates to high-voltage switch gear field operation.
Background technology
In the operation of high-voltage switch gear deciliter disconnecting link, generally require technical staff and in person operate, in operation, in order to Whether the operation of checking deciliter disconnecting link completes, and needs technical staff in person disconnecting link to be carried out electrical verification, easily occurs during electrical verification Misoperation causes casualties and economic impaired situation.
Summary of the invention
The present invention is to solve in the operating process carrying out high-voltage switch gear deciliter disconnecting link, generally require technical staff in person to disconnecting link Carry out electrical verification, casualties and economic impaired situation easily occur, it is proposed that a kind of sense for high-voltage switch gear deciliter disconnecting link Electricity voice prompting insulated pull rod device and using method thereof.
Electrification voice message insulated pull rod device for high-voltage switch gear deciliter disconnecting link includes pull bar and electrification suggestion device, described sense Electricity suggestion device is fixed in pull bar, and described pull bar includes holding rod, support bar and peg, and described holding rod is internal to be tied for hollow Structure, the outer surface of holding rod is pasted with insulating barrier, and support bar is vertically fixed on the top of holding rod, and peg is vertically fixed on support On the sidewall of bar, and described support bar and peg are conductor, and described electrification suggestion device includes that inductive probe, signal amplify and touches Power Generation Road, relay circuit, control circuit, drive circuit, phonation circuit, loudspeaker and power supply, inductive probe is for detection Strut and peg are the most charged, and the induced signal outfan of inductive probe and signal amplify the induced signal input of triggering circuit even Connecing, signal amplifies the signal output part that triggers of triggering circuit and is connected with the triggering signal input part of relay circuit, relay circuit Control signal outfan be connected with the control signal input of control circuit, the control signal outfan of control circuit with drive electricity The control signal input on road connects, and the control signal outfan of drive circuit is connected with the control signal input of phonation circuit, The audio signal output terminal of phonation circuit is connected with the audio signal input of loudspeaker, and power supply is for providing running voltage to each circuit.
It is by following mistake based on the above-mentioned using method for the electrification voice message insulated pull rod device of high-voltage switch gear deciliter disconnecting link Cheng Shixian's:
When carrying out sub-switching operation, will be separated by peg in disconnecting link high-tension line, inductive probe detection peg is the most charged, as Really peg is charged, and it is concurrent that high level is changed into low level by 10 pins of the CD4011 logical AND not gate that signal amplifies triggering circuit Send to touch and signal to relay circuit, the first relay and the second relay trigger action, the first relay normally open contact and second Relay normally open contact closes, and control circuit will send a control signal in drive circuit by the effect of crystal oscillator after one second, Drive circuit works, the 3rd relay normally open contact Guan Bi, phonation circuit sends acoustical signal to loudspeaker, and loudspeaker send prompt tone, Now showing that switch tool separates with high-tension line completely, if peg is not charged, then signal amplifies triggering circuit 10 pins of CD4011 logical AND not gate will not send triggering signal, the first relay and the second relay will not occur action, Loudspeaker will not send prompt tone, now shows that switch tool separates with high-tension line completely;
When carrying out closing operation, pushing in high-tension line by peg by disconnecting link, inductive probe detection peg is the most charged, If peg is charged, signal amplifies 10 pins of the CD4011 logical AND not gate triggering circuit and high level is changed into low level also Send to touch and signals to relay circuit, the first relay and the second relay trigger action, the first relay normally open contact and the Two relay normally open contact Guan Bis, control circuit will send a control signal in drive circuit by the effect of crystal oscillator after one second, Drive circuit works, the 3rd relay normally open contact Guan Bi, phonation circuit sends acoustical signal to loudspeaker, and loudspeaker send prompt tone, Now showing that switch tool constitutes path with high-tension line, if peg is not charged, then signal amplifies triggering circuit 10 pins of CD4011 logical AND not gate will not send triggering signal, the first relay and the second relay will not occur action, Loudspeaker will not send prompt tone, now shows that switch tool does not constitute path with high-tension line, does not complete closing operation.
Beneficial effect: the electrification voice message insulated pull rod device simple in construction for high-voltage switch gear deciliter disconnecting link that the present invention proposes, Easy to use, by peg, high-voltage switch gear deciliter disconnecting link is operated, it is ensured that pull bar insulate with human body, guarantees personal safety. Inductive probe detection peg the most charged, if charged, by signal amplify trigger circuit, relay circuit, control circuit and A series of actions of drive circuit, it will send alarm, without charged, then whole circuit all without generation action, Will not send alarm, technical staff thus may determine that whether the operation of deciliter disconnecting link completes, nothing in whole operating process Need technical staff's electrical verification in person, safe and reliable.

When carrying out closing operation, by peg (10), disconnecting link is pushed in high-tension line, inductive probe (1) detection peg (10) the most charged, if peg (10) is charged, signal amplifies CD4011 logical AND not gate (2-1) triggering circuit (2) 10 pins high level is changed into low level and sends triggering signal to relay circuit (3), the first relay (KA1) and Second relay (KA2) trigger action, the first relay (KA1) normally opened contact and the second relay (KA2) are normally opened to be touched Point Guan Bi, control circuit (4) will send a control signal to drive circuit (5) after one second by the effect of crystal oscillator (4-2) In, drive circuit (5) works, and the 3rd relay (KA3) normally opened contact Guan Bi, phonation circuit (6) is sent out to loudspeaker (7) Send acoustical signal, loudspeaker (7) to send prompt tone, now show that switch tool constitutes path with high-tension line, if peg (10) not charged, then 10 pins of CD4011 logical AND not gate (2-1) that signal amplifies triggering circuit (2) will not send Triggering signal, the first relay (KA1) and the second relay (KA2) will not occur action, loudspeaker (7) will not send and carry Show sound, now show that switch tool does not constitute path with high-tension line, do not complete closing operation.
