Abstract
The invention provides an isolation switch terminal bar test sensor comprising a sampling spring probe and a sensor data processing circuit which is connected with the sampling spring probe, wherein the sampling spring probe is connected with a probe fixing base. The sensor data processing circuit is installed beside the probe fixing base. The sensor data processing circuit is composed of a switching circuit formed by an input and output circuit and a diode AND gate circuit, and a sampling triggering circuit. The isolation switch terminal bar test sensor is easy to control so that the workload of testing can be reduced; and the same IO port can be used for high-level output and can also be used for data sampling through the sensor data processing circuit so that the problem of testing by searching a new high-level wiring port for a disassembling wire inputted to a high-level disassembling mechanism at the maintenance field can be greatly solved.
Description
Technical field
The invention belongs to electric line service kit field, particularly relate to a kind of electronic isolation switch terminal block test sensor.
Background technology
Isolation switch be in transformer station, electric line with chopper with the use of a kind of capital equipment.Isolation switch particularly bus isolation switch, both equipment in switch gap had been belonged to, also it is connected with bus, maintenance bus isolation switch bus power failure should also want switch gap to have a power failure, when this just gives the isolation switch motor drive mechanism fault that maintenance bus isolation switch brings sizable difficulty, particularly bus charging operation, it is impossible to checking test, make a lot of electronic isolation switch be in abnormal condition, bring the biggest hidden danger to operation of power networks.Meanwhile, electronic isolation switch secondary circuit components and parts are many, any one components and parts fault all will cause can not normal divide-shut brake, when particularly processing this type of fault, changed components and parts and cannot be carried out test.
Present stage, electronic isolation switch secondary circuit is tested the blank that always there is equipment and technology, there is no special test device.Test device takes data to be the difficult point of this test, the present invention just for this situation, R & D design electronic isolation switch terminal block test sensor.
Summary of the invention
For aforesaid technical problem, the invention provides a kind of isolation switch terminal block test sensor, the present invention tests the contact portion of sensor by isolation switch terminal block and isolation switch secondary circuit carries out data sampling and control signal output, the output of control signal carries out the switching of low and high level by sensing data process part, thus obtain the data sampling of two states, then exported to main frame by sensor information bus portion.
Technical scheme is specific as follows:
A kind of isolation switch terminal block test sensor, processes circuit including sampling spring probe, sampling spring probe linking probe firm banking and the sensing data being connected with sampling spring probe；Described sensing data processes circuit and is arranged on the side of probe firm banking, and switching circuit and sampling that wherein sensing data process circuit is made up of imput output circuit, diode AND gate circuit trigger circuit and form.
The isolation switch terminal block test sensor of the present invention, it carries out data sampling by sampling spring probe, sampling feedback information has Loss, sampling triggers circuit will ask for high level output I/O port numbering to main frame, corresponding output input circuit I/O port is switched to high level output pattern by sampling configuration by the switching circuit consisted of diode AND gate circuit, carry out secondary data sampling, the sample information of acquisition is transferred to main frame by the bus of sensor.
The isolation switch terminal block test sensor manipulation of the present invention is simple, alleviates the workload of this test；Process the same I/O port of circuit realiration by sensing data and can be used as high level output, again can be as data sampling, well solving Overhaul site is that input high level is torn mechanism open and taken out stitches and find the difficult problem that new high level Wiring port just can carry out testing.
Accompanying drawing explanation
Fig. 1 is isolation switch terminal block test sensor construction schematic diagram in the present invention；
Fig. 2 is that sensing data processes circuit diagram.
Detailed description of the invention
As it is shown in figure 1, the isolation switch terminal block test sensor of the present invention includes: sampling spring probe 1, probe firm banking 2 and sensing data for sensor contact portion process circuit.Wherein, sampling spring probe 1 is the part of contact isolation switch terminal block, and its bottom is fixed by probe firm banking 2, and chassis interior processes circuit equipped with 3 sensing datas.Process circuit 3 from the data of isolation switch terminal block input and output by sampling spring probe 1 and sensing data and carry out the transmission of data message.
As in figure 2 it is shown, sensing data processes the main switching circuit 5 being made up of imput output circuit 4, diode AND gate circuit of circuit 3 and sampling triggers circuit 6 and forms.Sampling is triggered circuit 6 and is connected with imput output circuit 4 by R1, and imput output circuit 4 connects switching circuit 5, electric capacity C and resistance R3 respectively, and audion Q connects resistance R3, electric capacity C, resistance R2 and sampling respectively and triggers circuit 6；The other end of described resistance R2 connects switching circuit 5.Imput output circuit 4 is connected with biography sampling spring probe 1, the information of acquisition and sampling triggering circuit 6 is swapped, and sampling triggering circuit 6 sends command signals to the switching circuit 5 of diode AND gate circuit composition and carries out power supply output and the switching of signals collecting.
Comprehensive above narration, the isolation switch terminal block test method of work of sensor of the present invention and work process be: is carried out data sampling by the sampling spring probe of sensor contact portion, the information of acquisition is sent to sampling by imput output circuit and triggers circuit, sampling triggers circuit judges whether send switching signal, if switching signal to be sent directly transmits the switching circuit that order forms to diode AND gate circuit, I/O port corresponding for imput output circuit is switched to the pattern of order request by switching circuit, thus the high level under completing switch mode drives sampling.
The scope of the present invention is limited by claims rather than described above, and all changes fallen in the implication of equivalency and scope of claim should be included in the present invention.Additionally, should not be considered as limiting involved claim by any reference in claim.
It is to be understood that, although this specification is been described by according to embodiment, but the most each embodiment only comprises an independent technical scheme, this narrating mode of description is only for clarity sake, those skilled in the art should be using description as an entirety, technical scheme in each embodiment can also form, through appropriately combined, other embodiments that it will be appreciated by those skilled in the art that.
