Abstract
The utility model relates to a timer for trip outlet time of a relay protection device. The timer comprises a single-chip microcomputer, wherein a signal input terminal of the single-chip microcomputer is connected with at least four test terminals respectively to detect on or off states of to-be-measured outlet nodes, the signal input terminal of the single-chip microcomputer is also connected with a starting signal terminal to acquire a timing beginning signal, and the single-chip microcomputer is connected with a display module. The timer can be cooperated with a relay protection tester which is used by working staff to determine time of multiple outlets of the relay protection device. The timer is characterized by light weight, small volume, and strong portability, which is very suitable for carrying by relay protection work staff. Besides verifying relay protection device, the timer can be applied to other timing fields, such as verifying time relay, determining time when a phase-splitting breaker is tripped out simultaneously, and the like.
Description
Technical field
The utility model relates to a kind of protective relaying device tripping operation outlet time calculagraph.
Background technology
The protective device tripping operation outlet time is meant from feed the simulated failure branch to protective device and measures to the All Time of protection action till isolating switch sends the tripping operation pulse, is exactly the actuation time that protective device is adjusted in fact.Protection equipment for transformer is because transformer itself can relate to the isolating switch of a plurality of electric pressures, so its protective device tripping operation also has a plurality of isolating switch outlets, so the outlet time also exists various.
For a long time, never have a kind of instrument and can measure a plurality of tripping operation outlet times simultaneously, the staff can only confirm the outlet time through observing actual phenomenon and protective relaying device message, and protective device tripping operation outlet time check lacks intuitive and accuracy.
The utility model content
The purpose of the utility model provides a kind of protective relaying device tripping operation outlet time calculagraph, can measure the time of a plurality of outlets of protective relaying device simultaneously.
A kind of protective relaying device tripping operation outlet time calculagraph; Its special feature is; Comprise single-chip microcomputer; Thereby the signal input port of this single-chip microcomputer is connected the switching of checking outlet node to be measured with at least 4 test leads respectively, thereby the signal input port of this single-chip microcomputer also is connected with signal end at the beginning and obtains the timing commencing signal, and this single-chip microcomputer also is connected with a display module.
Wherein display module is the charactron display module.
Can cooperate with the relay protection microcomputer test instrument that the test job personnel use after adopting this calculagraph, measure the time of a plurality of outlets of protective relaying device with this.Instrument itself has in light weight, and the characteristics that volume is little are portable strong, is fit to very much the relay protection staff and carries.Except that being used for the protective relaying device verification, also can be used for the field that other need minute, the for example verification of the time relay, the mensuration of the phase-splitting circuit breaker trip time same period etc.
Description of drawings
Accompanying drawing 1 is the logic theory block diagram of the utility model;
Accompanying drawing 2 is the main control process flow diagram of single-chip microcomputer in the utility model.
Embodiment
As shown in Figure 1; A kind of protective relaying device tripping operation outlet time calculagraph; Comprise single-chip microcomputer; Thereby the signal input port of this single-chip microcomputer is connected the switching of checking outlet node to be measured with at least 4 test leads respectively, thereby the signal input port of this single-chip microcomputer also is connected with signal end at the beginning and obtains the timing commencing signal, and this single-chip microcomputer also is connected with a display module.Wherein display module is 7 sections charactron display modules.
The commencing signal end is connected with relay protection microcomputer test instrument output contact and obtains the timing commencing signal during use, thereby a plurality of test lead is connected the switching that inspection exports node with protective device tripping operation outlet.
Claims (2)
1. protective relaying device tripping operation outlet time calculagraph; It is characterized in that: comprise single-chip microcomputer; Thereby the signal input port of this single-chip microcomputer is connected the switching of checking outlet node to be measured with at least 4 test leads respectively; Thereby the signal input port of this single-chip microcomputer also is connected with signal end at the beginning and obtains the timing commencing signal, and this single-chip microcomputer also is connected with a display module.
