Description
One, technical field: the utility model relates to a kind of tester, particularly relates to a kind of multifunction switch checked for characteristics instrument.
Two, background technology: along with the development of society; people require more and more higher to the safe reliability of electricity consumption; a large amount of primary cut-outs that use are being undertaken the dual role of control and protection in electric system, the quality of its performance is directly connected to the safe operation of electric system.The mechanical property parameter is to judge the important parameter of isolating switch performance.Switch machinery characteristic tester is exactly an instrument of measuring the mechanical dynamic performance parameters of isolating switch.Generally be divided on the structure and carry operating power and make two kinds of power supplys with ribbon gymnastics not, and ribbon gymnastics is not divided into as power supply two kinds of relay and non-relays is arranged, be called " active " that relay is arranged, being called of non-relay " passive type ", is in the market because the kind of switch machinery characteristic tester is more, thereby calibration steps is more and disorderly and unsystematic aspect calibration switch testing mechanical characteristic instrument, and a standard can not be calibrated various types of switch machinery characteristic testers.
Three, utility model content:
Technical problem to be solved in the utility model is: provide a kind of volume little, in light weight, be easy to carry and the on-the-spot multifunction switch checked for characteristics instrument that uses and realize a tractor serves several purposes.
The utility model is that the technical scheme that the technical solution problem is taked is:
A kind of multifunction switch checked for characteristics instrument, contain casing and control circuit, described casing is provided with the stop signal port, the enabling signal port, start/stop the voltage selector button, dial and LED display, be provided with described control circuit in the described casing, this control circuit contains power module and time measurement module, described time measurement module mainly comprises single-chip microcomputer, connect driving circuit on the I/O bus of described single-chip microcomputer, this driving circuit is connected with LED display, connect two level shifter interfaces on the I/O bus of described single-chip microcomputer in addition, described two level shifter interfaces respectively with enabling signal port and stop signal port, and described single-chip microcomputer also respectively with dial, start/stop the voltage selector button, described dial can preset respectively and close, opening time, bounce time, described power module adopts direct-current switch power supply, is connected with the enabling signal port as required.
Described single-chip microcomputer is 89C52, and described power module is the direct-current switch power supply of 0～250V.
Positive beneficial effect of the present utility model is: can power module and time measurement module is integrated, realize the accurate instrument of a station symbol just the closing of the various switches of verification machinery characteristic tester, opening time, bounce time and three-phase synchronism easily.Particularly be applied in the metering field to have good practicality and economic benefit after the popularization for the isoparametric measurement of switching characteristic tester time.
Four, description of drawings:
Fig. 1 is the circuit block diagram of multifunction switch checked for characteristics instrument.
Five, embodiment:
Embodiment: referring to Fig. 1, among Fig. 1, multifunction switch checked for characteristics instrument contains casing and control circuit, casing is provided with the stop signal port, the enabling signal port, start/stop the voltage selector button, dial and LED display, be provided with control circuit in the casing, this control circuit contains power module and time measurement module, the time measurement module mainly comprises single-chip microcomputer, connect driving circuit on the I/O bus of single-chip microcomputer, this driving circuit is connected with LED display, connect two level shifter interfaces on the I/O bus of described single-chip microcomputer in addition, two level shifter interfaces respectively with enabling signal port and stop signal port, and described single-chip microcomputer also respectively with dial, starting/stop the voltage selector button connects, described dial can preset respectively and close, opening time, bounce time, described power module adopts direct-current switch power supply, is connected with the enabling signal port as required.Single-chip microcomputer is 89C52, and power module is the direct-current switch power supply of 0～250V.
Principle of work: selected to start and stop voltage by school switch machinery characteristic tester according to difference, dial can preset respectively and close, opening time, bounce time; Issue a signal to the enabling signal port by the direct supply that is calibrated instrument or this instrument, single-chip microcomputer is received the triggering level signal from the enabling signal port and is picked up counting, after preset time arrives, single-chip microcomputer sends level signal to the stop signal port, be calibrated instrument and stop timing, be calibrated instrument simultaneously and show that time, single-chip microcomputer are by the driving circuit driving LED screen display standard time.The standard time of realizing this multifunction switch checked for characteristics instrument so just can calibration switch testing mechanical characteristic instrument multiple time-parameters.
Multifunction switch checked for characteristics instrument of the present utility model can be integrated with power module and time measurement module, realize the accurate instrument of a station symbol just the closing of the various switches of verification machinery characteristic tester, opening time easily, bounce time and three-phase synchronism; Particularly be applied in the metering field to have good practicality and economic benefit after the popularization for the isoparametric measurement of switching characteristic tester time.
