Abstract
The utility model relates to a device for detecting the switch on or switch off condition of a breaker in a leakage breaker integrated test bench, which comprises a relay, an optical coupler, an industrial control computer, a direct-current main and a display device, wherein the normal opened contact of the relay is connected in series with the direct-current main and a terminal that connects the contactors in the input and output ends of the breaker to be detected, and then connects the first pole and the secondary pole of the optical coupler to connect the industrial control computer, the display device is connected with the industrial control computer either. The monitoring of whether the breaker being detected is in the switch on or switch off condition is achieved in an integrated test of the leakage breaker utilizing the circuit in the utility model and utilizing the direct-current main instead of the AC supply. The judgment is accurate and reliable when monitoring the switch on or off condition of the breaker being detected for direct current signal has no zero-crossing blind district, and the response speed is quick, thereby further ensures the monitoring reliability of the switch on or off condition.
Description
Affiliated technical field
The utility model belongs to a kind of breaker test stand, particularly relates to a kind of integrated test bench for creepage breaker and detects isolating switch on/off switch situation device.
Background technology
In the present known process that isolating switch is tested, need the on/off switch device isolating switch is carried out repeatedly the on/off switch operation, be in "on" position or gate-dividing state for tested isolating switch in the process of the test in the integrated test bench for creepage breaker that disclosed number of patent application is 200610013115.X, lack Presentation Function, therefore relatively difficult when needs determine that tested isolating switch is in "on" position or gate-dividing state as the personnel that test.
The utility model content
The utility model provides a kind of integrated test bench for creepage breaker to detect isolating switch on/off switch situation device for solving the technical matters that exists in the known technology.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is: it includes relay, optocoupler, industrial control computer, direct supply and display device; The normal opened contact of relay and direct supply and the terminal serial connection that is connected tested isolating switch input and output contact and the first utmost point of serial connection optocoupler, the optocoupler time utmost point links to each other with industrial control computer; Described display device also links to each other with industrial control computer.
The utility model can also adopt following technical measures:
Described industrial control computer also can be single-chip microcomputer or PLC.
The advantage that the utlity model has with good effect is: owing to adopted the normal opened contact of relay to link to each other with industrial control computer with the terminal serial connection back that is connected tested isolating switch input and output contact with direct supply, and corresponding display device; With replace AC power with direct supply, realized in the residual current circuit breaker compbined test, tested isolating switch being in the "on" position or the supervision of gate-dividing state.And when monitoring tested isolating switch on/off switch state, because of direct current signal does not have the mistaken ideas of zero crossing, accuracy of judgement is reliable, and response speed is fast, the reliability that further guaranteed to close, gate-dividing state monitors.
Description of drawings
Fig. 1 is circuit theory diagrams of the present utility model.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, the DC loop that the isolating switch on/off switch detects is by+a normally opened contact of 12V direct supply serial connection relay J 34, the terminal of isolating switch input and output contact, be connected in series another normally opened contact of relay J 34 again, connect again optocoupler in the digital quantity input port driving circuit elementary after, insert the 0V end at last.It is secondary that the digital quantity input port P1 of industrial control computer connects optocoupler, and the digital quantity output port P0 of industrial control computer succeeds electric apparatus coil.Industrial control computer also is connected to display.
The detection loop of the isolating switch on/off switch detection that constitutes like this, in the circuit-breaker testing process, during as breaker closing when the closing of contact between isolating switch GO2, the GO6, industrial computer digital quantity output port P0 gets the coil of relay J 34, this normally opened contact closure, then direct current 12V is through isolating switch, after the elementary conducting of optocoupler, the then secondary conducting of optocoupler, behind the industrial computer digital quantity input port P1 incoming level signal, the proof breaker closing is reliable, and the animation effect of breaker closing state is presented on the display screen.If isolating switch is in separating brake or dropout position, then should detect the loop and disconnect, the optocoupler of the digital quantity input port driving circuit just utmost point ends, and then time utmost point ends, and low level signal is imported the industrial computer dispatch control system.Industrial computer closes the branch position by what high-low level was judged isolating switch, and is shown by display device.
