In fact, every manufacturer hopes to have a very good test value and very good quality when choosing a switching characteristic tester, so as to ensure that they have a higher value in the whole process of use, and the same is true for choosing a high-voltage switching characteristic tester. Because many people do not know much about the information of the high-voltage switching characteristics tester before choosing, but their choice is not good, in fact, when you really choose the high-voltage switching characteristics tester, you will find that its quality is excellent, and it is very worthy of everyone's choice.

The manufacturer also hopes that the quality of the high-voltage switching characteristic tester produced by itself is very good, and there is a very good sales volume in the market, which can solve various problems for customers, and can have a qualitative market influence, and can show a very good foundation for the next development of the factory. Therefore, in the selection of the initial design scheme, many details will be taken into account, for example, the impact of the environment, the influence of the material, although even the final cost factor is considered, it is natural to ensure that the production of high-voltage switching characteristics tester has a very stable performance, and has a very high cost performance, which is very in line with every customer to choose. Therefore, it is said that the high-voltage switching characteristics tester has a very good quality, and the accuracy of the detection will not be reduced due to quality problems when testing the equipment.

Then you only need to consider the style and model of your own factory equipment when choosing a high-voltage switching characteristic tester, and then find a good manufacturer to buy a batch of high-voltage switching characteristic testers, so that you can detect your own equipment problems under the correct operation, and you can also know how to solve all the problems and restore the normal production of the factory.

Huatian Electric Power specializes in the production of high-voltage switching characteristics tester, which is your trustworthy choice, and you are welcome to consult with all power workers.

Jiangsu Huafang Electric Technology Co., Ltd. specializes in the production of power testing instruments including switch tester and high-voltage switching characteristic tester. As for which manufacturer is good! This should be looked at from many aspects:

1. Of course, the product is good, and there are many manufacturers in Jiangsu Baoying: such as Santuo Test Instrument Factory, SEG and other personal workshops, it should be said that the quality will not be too bad. Santuo did it earlier; Experience is a little better.

2. I think after-sales service is very important, there will be some small problems in the products produced by a manufacturer more or less (no matter how big the brand is, is the Apple mobile phone good, doesn't it also have after-sales service?) Therefore, the after-sales service is good, keep up, and actively solve problems for customers, I think this is a good manufacturer;

3. The above two are good to add ** good, which is really good, but there are really not many such manufacturers.

Based on the above three items, you can only choose the total score to judge for yourself.

The working principle of the high-voltage switch mechanical characteristics tester is as follows:

1. The simulated leakage current emitted by the detector uses a step-down transformer to output a low-voltage current.

The step-down output primary input voltage of the simulated leakage current is controlled by the potentiometer regulating terminal, that is, the primary voltage of the input transformer is gradually increased from zero through the potentiometer adjustment, and the secondary output transformer simulates the leakage current and gradually increases. This makes it possible to test the operating current characteristics of leakage repairs.

The action current and time tests for leakage repairs are controlled by the test button on the machine panel. When the test button is pressed, on the one hand, an analog leakage current is output, and at the same time, the electrical signal can trigger the timing milliseconds, so when the leakage switch is activated, the recorded time is the running time when the leakage current is applied.

2. The machine panel is equipped with machine power socket, quick-break fuse, test line socket, power switch, adjustment knob, function switch, reset button, test button, digital display milliampere meter, millistopwatch, etc.

Briefly analyze the working principle of the high-voltage switch mechanical characteristics tester. The zero sequence transformer is not in the case of a leakage holder. Characteristic measurement of maintenance personnel 1

Preparation before the test Before the tester is connected to the power supply, the "power switch" of the instrument should be in the disconnected position, and the power supply should be connected to the power side maintainer (AC220V) of the leakage power, and the phase wire and neutral wire should not be connected wrong. The test line passes through the zero sequence transformer and is connected to the non-inverting wire of the tester power supply. The function switch of the tester is placed in the "preset" position.

After confirming that the wiring is correct, turn the "Current Regulation" potentiometer on the tester panel counterclockwise to zero and press the "Power Switch". At this point, the indicator of the milliampere and millistopwatch should be zero, if not, just press the "Reset" key.

3. Measurement of leakage current or leakage without action current of the leakage holder itself (the lead wire on the load side should be disassembled, and the function switch should be placed in the "preset" position. After the leakage holder is put in, press the test button at this time, and slowly adjust the "current regulation" potentiometer on the tester panel clockwise, the MA meter of the tester should show the MA value, and the current will gradually increase until the leakage protector acts. At this point, the milliampere meter shows a reading of leakage current.

High-voltage circuit breaker is an important control device in the power system. The operation of high-voltage circuit breakers in the power grid is the largest, and the operating conditions and technical requirements are relatively complex, and its operation reliability is not only related to the high-voltage circuit breaker itself, but also affects other equipment and even the entire power grid. Therefore, it is a very important work to test the dynamic characteristics of the high-voltage circuit breaker, but there are shortcomings such as complex operation and low test accuracy when the traditional method is used to test the dynamic characteristics of the high-voltage circuit breaker.

Based on the high-performance industrial embedded platform, it has high-speed data acquisition, analysis and processing capabilities, can resist strong electromagnetic field (more than 500kV) interference, and has the characteristics of multi-channel high-voltage switching characteristics and high analysis and testing accuracy. According to the different test requirements of different switches, this instrument has rich and complete user-defined functions. This instrument has a built-in isolated adjustable DC power supply and switch operation command, and the switch opening, closing and reclosing operation can be directly controlled by the built-in DC power supply during the test, and it has the function of automatic or manual action voltage test.

This instrument can carry out various types of high-voltage switches related to mechanical characteristics of parameters (time, speed, synchronous, stroke, bounce, coil current, etc.) testing and characteristic analysis.
