Technical Field

[0001] The utility model relates to the technical field of aging testing, in particular to a relay aging testing device. Background Art

[0002] A three-phase AC voltage monitoring relay is an electronic device used to monitor the voltage of a three-phase AC power supply. It samples and analyzes the three-phase AC voltage in real time. When it detects voltage anomalies such as overvoltage, undervoltage, phase loss, or phase sequence errors, it triggers corresponding alarms or protection actions.

Most existing aging test equipment can only perform aging tests on a single relay. Equipment that can perform aging tests on multiple relays is generally large in size, which leads to a large space occupation and causes inconvenience in operation. Utility Model Content

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0026] like Figure 1-Figure 3 As shown, in one embodiment, a relay aging test device includes a working frame 1, working panels 2 are provided on both sides of the working frame 1, and each working panel 2 is provided with a plurality of test units 3, in which the product to be subjected to aging test, i.e., the relay, can be placed.

[0027] An AC transformer is provided inside the working frame 1, and a plurality of voltage regulators 4 are provided on the side of the working frame 1. The voltage regulators 4 are used to adjust the three-phase voltages respectively. A voltmeter 5 is provided on the side of the working frame 1, and the voltmeter 5 is used to check the three-phase voltage values. Specifically, the AC transformer can reduce the external voltage to match the operating voltage of the aging test equipment. The voltage regulator 4 is electrically connected to the test unit 3 and the AC transformer. By adjusting the three voltage regulators 4, the voltage of each phase can be adjusted, so that different voltages can be set according to actual needs for aging testing. By setting the voltmeter 5, the voltage of each phase of the power supply of each product can be monitored. At the same time, the monitoring function of the product for three-phase imbalance can be tested by adjusting the voltage regulator 4. A time relay 6 is also provided on the side of the working frame 1. Setting the time relay 6 can automatically record the aging time or the preset aging time function.

[0028] Optionally, a phase sequence control knob 7 is provided on the side of the working frame 1, and the phase sequence control knob 7 is electrically connected to the three-phase AC power supply and the test unit 3. The phase sequence control knob 7 is used to control the phase sequence of the three-phase AC power supply.

[0029] Optionally, the voltage regulator 4 is a contact-type voltage regulator 4 that can adjust the three-phase voltage separately. At the same time, the voltage values ​​of each phase, L1, L2, and L3, can be checked through a voltmeter 5. There are also L3-L1 switching and L1 power-off toggle switches, which can be used to test the product for phase mismatch, phase reversal, phase loss, and three-phase imbalance.

[0030] Optionally, the working frame 1 is a vertical structure, and its overall structure is a flat structure. Two working panels 2 are symmetrically arranged on both sides of the working frame 1. The size of the working panels 2 is relatively large. Specifically, the size of the working panels 2 is roughly the same as the surface size of the working frame 1. At least 50 test units 3 are arranged on each working panel 2, and a total of 100 test units 3 on both sides. When the three-phase AC voltage monitoring relay needs to be tested, it is only necessary to place the relay in the test unit 3 to perform an aging test on it. Through the above-mentioned setting, the aging test of the three-phase AC voltage monitoring relay can be carried out in batches, which greatly improves the efficiency of the aging test for batch products. At the same time, since the entire frame is a vertical flat structure, it occupies less space and is more convenient for loading and unloading operations.

[0031] Optionally, a roller 11 is provided at the bottom of the working frame 1. The roller 11 is preferably a universal wheel, which can be easily moved to a position to be measured.

[0032] Optionally, the test unit 3 includes a fixing base 301 fixed to the working panel 2. The fixing base 301 is provided with a handle plate 302, which is fixed to the fixing base 301 by a spring 303. The handle plate 302 is provided with a probe 304, and the probe 304 is electrically connected to the product to be tested 305. During use, the product to be tested 305 is placed in the test unit and connected to the probe 304, thereby achieving power supply for subsequent testing.

[0033] Optionally, the probe 304 is wrapped with a protective cover 8, which can be made of transparent acrylic material. It can protect the probe 304, facilitate observation of the internal situation of the probe 304, and protect the operator from electric shock.

[0034] An indicator light 10 is provided on one side of each test unit 3. The indicator light 10 is used to light up and alarm when problems occur during the aging test. Specifically, the indicator light will light up and alarm when problems occur in the product during the aging process, which is convenient for quickly locating defective products.

[0035] Optionally, a door 9 is provided on the side of the working frame 1, and the door 9 is connected to the working frame 1 through a hinge. When the equipment fails, the cabinet can be opened to check the internal transformer, wiring, etc. The voltage regulator 4, the voltmeter 5, the time relay 6 and the phase sequence control knob 7 are integrated on the door 9, and the degree of integration is higher.
