Description
Technical field
The present invention relates to a kind of State-Inspect of High-Voltage Circuit device, belong to power measuring instrument instrument field.
Background technology
Most transformer stations have all realized unmanned, therefore need to carry out remote monitoring to deciliter state of the isolating switch of transformer station, switch etc., mainly be the state auxiliary contact that carry by monitoring breaker to the monitoring of circuit-breaker status at present, because deciliter state interlock of state auxiliary contact and isolating switch, can give dry contact of other switching value monitoring equipments, in order to circuit-breaker status is monitored.There are two shortcomings in such monitoring method, and the one, although monitored deciliter state of isolating switch, whether monitoring has voltage less than the isolating switch outlet, that its real user is concerned about most is the latter; The 2nd, isolating switch needs the installment state auxiliary contact, not only take rack front panel space, and cost is higher.
Summary of the invention
According to above deficiency of the prior art, the technical problem to be solved in the present invention is: the State-Inspect of High-Voltage Circuit device of provide a kind of low cost, easily realizing.
The technical solution adopted for the present invention to solve the technical problems is: a kind of State-Inspect of High-Voltage Circuit device is provided, it is characterized in that, comprise input circuit, resistor voltage divider circuit, mu balanced circuit, signal output apparatus, input circuit contact resistance bleeder circuit, resistor voltage divider circuit connects signal output apparatus by mu balanced circuit.
Input circuit is rectification circuit, comprises commutation diode D1 ~ D4, and commutation diode D1 is in parallel with commutation diode D2, and commutation diode D3 is in parallel with commutation diode D4, and commutation diode D1 links to each other with commutation diode D4, and commutation diode D2 links to each other with D3.

Input circuit carries rectification circuit, so input terminal voltage needn't be distinguished both positive and negative polarity.
If the exit of isolating switch is charged, then its input voltage is higher, and rated voltage is DC250V, output light lotus root two ends only need the voltage about 3V to get final product, and therefore, input circuit part needs the resistance of larger resistance and power, just can share unnecessary voltage, guarantee the reliable and stable work of circuit.
Mu balanced circuit of the present invention is comprised of stabilivolt and electric capacity, the voltage constant that makes light lotus root control end is 3V, light lotus root control end needs an electrochemical capacitor in parallel and a ceramic disc capacitor, even being input terminal voltage, purpose changes, also can not affect the steady operation of light lotus root, guarantee the stability of output signal.
The exit of input circuit connecting breaker, if the isolating switch outlet has voltage, light coupling relay output high level signal; If the isolating switch outlet does not have voltage, light coupling relay output low level signal.Output signal has shown deciliter state of isolating switch, as the input signal of switching value monitoring equipment.
