5、 Instrument Introduction

1. Introduction to Instrument Appearance

2. Instrument self checking method

Connect the transmitter to the self-test test line as shown in the diagram. The transmitter will start, the buzzer will sound, and the red and green indicator lights will flash alternately. If the receiving host is turned on and displays the corresponding transmitter information in the close range nuclear phase mode, then both the transmitter and the host are working normally.

Hint:

（1）During self inspection, the distance between the two transmitters and the receiving host is greater than0.5 meters is suitable. When the distance is less than 0.2 meters, only one transmitter may be connected while the host displays information from two transmitters. This phenomenon is normal and does not affect the use of the instrument. When both transmitters are powered on, the instrument display is not affected by short distances.

（2）There is a string inside the self checking test line2MResistance, during testing, human contact with crocodile clips will not result in electric shock.

（3）The self check test phase difference is180When the degree is around, reverse the plug of any self checking line, and the phase difference will become0Left or right, and vice versa.

6、 Short-range nuclear phase

1High voltage transmission line core phase (high-voltage core phase)

Translate into EnglishConnect the X and Y transmitters to insulating rods and hang them on the high-voltage line. When the receiving host is turned on and selects the close range phase detection mode, the phase detection results can be displayed and broadcasted. The schematic diagram is as follows:

2High voltage switchgear live display phase (low voltage phase)

Translate into EnglishReplace the X and Y transmitter hooks with pointed terminals and insert them into the live display. Then, insert the DC end of the grounding wire into the transmitter grounding hole (which is also a charging hole), connect the crocodile clip to the ground, and select the close range phase detection mode when the receiving host is turned on for measurement. The usage method of the transmitter is shown in the following figure:

Hint:Due to the fact that the main function of a live display is to indicate whether the switchgear is live, rather than a standard phase point, and that live displays from different manufacturers, periods, and standards may have varying degrees of phase shift issuesThe correspondence between L1, L2, L3 and the busbar may not be correct. If the phase verification result is abnormal, phase verification should be performed on the primary line.

7、 Result judgment and analysis

The result judgment adopts the national standardStandard, with 30 ° as the boundary for homogeneity and heterogeneity. phase difference≥±30°Time is out of phase, voice prompt'Out of phase', the screen displays' out of phase ', and the out of phase indicator light is on.phase difference<±30°Same phase, voice promptSame phase ", the screen displays" Same phase ", and the same phase indicator light is on. All phase difference results are based on X, with Y being the phase ahead of X.

Tip: When the frequencies of two lines are different, a quasi synchronous parallel device needs to be used to control the frequency phase of the generator, so that the phase and frequency of the generator are consistent with the main grid before it can be connected to the grid for power transmission. Parallel operations of quasi synchronous and self synchronous are shown in the appendixB.

AppendixB

The synchronization methods for generator grid connection are divided into quasi synchronization and self synchronization

Quasi synchronous parallel operation is the process of adding excitation to a generator that has not been put into the system, and adjusting its voltage and frequency. When the parallel conditions are met (i.e., voltage, frequency, and phase are the same), the generator is put into the system. If the outlet switch of the generator is closed under ideal conditions, the circulating current in the stator circuit of the generator will be zero, which will not generate current and electromagnetic torque impact.The quasi synchronous parallel time is long, but the impact is small. Large generators should adopt a quasi synchronous method.

Starting from synchronous parallel operation, first turn on the wheel generator set. When the speed rises slightly below the rated speed of the unit, close the circuit breaker,At this time, the power system sends three-phase impulse current to the stator winding of the generator to form a rotating magnetic field, and then the excitation system sends DC current to the rotor winding of the generator to generate a magnetic field, causing the power system to pull the generator into synchronous operation. During the parallel process, the generator suffers certain damage due to the impulse current, which is the disadvantage of self synchronization. The advantage is that the parallel process is relatively fast.Short parallel time from the same period, suitable for the integration of small hydropowerThe internet.
