Description

Technical Field

[0001] The utility model relates to the technical field of jumper detection, in particular to a high-efficiency excitation system jumper conduction detection auxiliary device. Background Art

[0002] The generator excitation system jumper consists of a set of forward and reverse thyristors connected in series with a deexcitation resistor to the positive and negative poles of the rotor. A rotor overvoltage detection board is also connected in the circuit. When the rotor overvoltage or an accidental shutdown occurs, the jumper is triggered to conduct, rapidly dissipating rotor energy in the deexcitation resistor, reducing rotor current and generator terminal voltage. The performance of the excitation system jumper directly determines whether the excitation system can reliably deexcite, which also places higher demands on jumper maintenance.

[0003] Currently, there are two methods for testing jumper performance. One involves connecting a jumper to the rotor overvoltage circuit and using a test instrument to simulate rotor overvoltage. When the rotor overvoltage plate activates, the jumper is triggered to conduct. The oscilloscope waveform is then used to determine whether the rotor overvoltage plate is functioning properly, whether the jumper is conducting, and whether it is functioning properly after conduction. The other method involves applying a voltage across the jumper and observing the change in leakage current after the voltage increases. Jumper performance is then determined based on the leakage current. Jumper performance is checked on-site through the rotor overvoltage test and the jumper leakage current test. During these tests, high voltage is applied across the components, and improper operation can easily damage the components. Both methods require highly specialized technical expertise to interpret the test results, and the jumper's conduction status cannot be directly determined. Furthermore, the peak voltage during the rotor overvoltage test is typically around 3200V. Improper operation at high voltages can cause component burnout and pose a high risk of electric shock. Utility Model Content

[0004] The purpose of the utility model is to provide an efficient excitation system jumper conduction detection auxiliary device, which aims to solve the problem that when testing with the existing method, it is necessary to use an oscilloscope to observe the jumper conduction waveform and judge whether the jumper is conductive, which requires high professional technical identification ability of technicians and is not intuitive enough.

[0005] The present invention is achieved through the following technical solutions:

[0006] An efficient excitation system jumper conduction detection auxiliary device comprises: a housing, a switching assembly, an indicator assembly, and a power supply assembly, wherein the switching assembly and the indicator assembly are both arranged on the surface of the housing, a test terminal is arranged on the surface of the housing, and the power supply assembly is arranged inside the housing;

[0007] The two ends of the switching component are respectively connected to one end of the indicating component and one end of the test terminal, and the power supply component is respectively connected to the other end of the indicating component and the other end of the test terminal;

[0008] The switching component is used to control the on / off of a detection circuit formed by connecting the switching component, the indicating component, the power supply component and the test terminal.

[0009] Optionally, the housing is provided with openings or slots corresponding to the switching component, the indicating component and the test terminal.

[0010] Optionally, identifications or indicators corresponding to the switching component, the indicating component and the test terminal are provided on the surface of the housing.

[0011] Optionally, the shell is made of insulating material.

[0012] Optionally, the switching component is a two-position self-holding switching switch.

[0013] Optionally, the indicating component is a light emitting diode.

[0014] Optionally, the power supply assembly is composed of several batteries connected in series.

[0015] Optionally, a charging interface is provided on the shell, and the charging interface is connected to the power supply assembly.

[0017] Optionally, a low-battery reminder component is further included, which is connected to the power supply component; wherein the low-battery reminder component is used to determine the remaining power of the power supply component according to a preset threshold and issue a low-battery warning signal.

[0018] The technical solution of the embodiment of the utility model has at least the following advantages and beneficial effects:

[0019] Improved intuitiveness: By introducing an indicator component, when the detection circuit is closed and the jumper is conductive, the indicator component can directly light up, thereby intuitively reflecting the conductive state of the jumper. This allows operators to quickly and accurately determine the working status of the jumper without relying on complex oscilloscope waveform analysis, significantly improving the intuitiveness and convenience of detection.

[0020] Enhanced safety: The housing is made of insulating material and features a built-in power supply rather than an external high-voltage source, effectively reducing the risk of electric shock and equipment damage. The self-holding function of the switching component also prevents continuous circuit conduction caused by misoperation, further improving operational safety.

[0021] Improved detection efficiency: The test terminals use a spring terminal design, which simplifies the connection steps and speeds up the detection process. In addition, the conduction status of the jumper can be determined by directly observing the on and off status of the indicator component, eliminating the need for complex waveform analysis and professional skills, greatly improving detection efficiency.

[0022] Portability and flexibility: The entire device is compact and easy to carry to the site for testing. At the same time, the charging port design allows the power supply component to be easily charged, extending the use time of the device and enhancing its portability and flexibility.

[0023] Improved intelligence: By introducing a low-battery reminder component, the remaining power of the power component can be monitored in real time, and a warning signal will be issued when the power is lower than the preset threshold, reminding the user to charge or replace the battery in time, thereby avoiding the detection interruption problem caused by insufficient power and improving the intelligence level of the device and user experience.

The marks or indicators corresponding to the switch assembly 2, the indicator assembly 3, and the test terminal 5 facilitate correct operation and use by the user.

[0032] In this embodiment, the housing 1 can be made of insulating material. The housing 1 made of insulating material has waterproof, dustproof and anti-electric shock safety protection functions, ensuring the safety and stability of the components inside the housing 1 while also ensuring the safety of the operator.

[0033] In this embodiment, the switch assembly 2 can be a two-position self-holding switch. The switch assembly 2 can also be a push-button two-position switch. The switch assembly 2 has a self-locking function. After switching to the closed state, it can maintain the closed state until the user operates it again, thereby improving the convenience and safety of use.

[0034] In this embodiment, the indicator component 3 may be a light-emitting diode. The indicator component 3 may also be a component with an indication function, such as a buzzer or a low-voltage light-emitting element. When the detection circuit is closed and the jumper is conductive, the indicator component 3 intuitively reflects the conductive state of the jumper. The operator can intuitively determine the conductive state of the jumper based on the indicator component 3, thus realizing visualization of the jumper conductive detection and improving detection efficiency.

If the indicator component 3 is lit, it indicates that the jumper is conducting; when the output voltage of the rotor overvoltage tester 7 is reduced until the output voltage of the rotor overvoltage tester 7 is 0V, if the indicator component 3 remains lit, it means that the high voltage power supply output by the rotor overvoltage tester 7 did not damage the jumper during the overvoltage test, thereby judging that the working performance of the jumper is intact; if the indicator component 3 is off, it indicates that the jumper has malfunctioned during the overvoltage test.
