[0019] A test instrument 23 can be movably installed on the test body 22, and four groups of test instruments 23 are provided. A connecting socket 24 is fixedly connected to the test body 22, so as to fix and store the test instrument 23. In the default state, the test instrument 23 is electrically connected to the test body 22. When in use, one end of the connecting line is connected to the electrical equipment to be tested, and the other end is connected to the connecting socket 24 to perform an electrical test on the electrical equipment to be tested. For special circumstances, such as when the connecting line is too short or the test space is small, the test instrument 23 can be removed separately, and then connected to the equipment to be tested and the test instrument 23 through the connecting line, or the electrical equipment can be directly tested to achieve an electrical test.

[0020] It should be noted that the test instrument 23 includes a voltmeter, an ammeter and two sets of current sensors; the connecting wires are existing technologies, and the connecting wires include connecting wires for connecting the electrical equipment with the test instrument 23 and for measuring the temperature of the electrical equipment, and one end of the connecting wire for measuring the temperature of the electrical equipment is fixedly connected to a temperature sensor; the connecting socket 24 includes a connecting socket 24 for connecting the electrical equipment with the test instrument 23 and for measuring the temperature of the electrical equipment.

Five groups of alarm lights 28 are provided, corresponding to four groups of test instruments 23 and temperature sensors respectively. The display screen 26 is electrically connected to the test instrument 23, and is used to display the test results.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, movable grooves 7 are opened on both side walls of the lower shell 1, and four groups of movable grooves 7 are provided. The limit assembly is arranged in the movable groove 7, and the limit assembly includes a limit rod 10. A slide plate 8 and a spring 9 are arranged in the movable groove 7. The slide plate 8 is slidably connected to the lower shell 1. The upper end of the spring 9 is fixedly connected to the lower shell 1, and the lower end is fixedly connected to the slide plate 8. The limit rod 10 is arranged at the center of the spring 9 and the slide plate 8 and is rotatably connected to the slide plate 8. The bottom of the limit rod 10 passes through the lower shell 1 and is fixedly connected to the limit block 11. The limit block 11 is in a long strip shape. The side wall of the limit rod 10 is fixedly connected to a fixed rod 12, and the fixed rod 12 is arranged between the slide plate 8 and the lower shell 1. The fixed rod 12 is hinged with a connecting rod 2 13, and the two groups of connecting rods 2 13 on the same side are fixedly connected with a steering rod 14.

[0023] like Figure 2 , Figure 3 and Figure 4As shown, a placement slot 19 is provided at the bottom of the lower shell 1, and five groups of placement slots 19 are provided. The support assembly is provided in the placement slot 19, and the support assembly includes a hinge seat 15, and a limiting hole 17 is provided on the side of the hinge seat 15. The limiting hole 17 is a long strip, and a limiting slot 27 is provided on the side of the hinge seat 15. A support leg 16 is detachably and slidably connected in the limiting slot 27. The support leg 16 is slidably connected to the hinge seat 15. A support seat 18 is hinged at the bottom of the support leg 16, and the support seat 18 is used to support the box body. It is also suitable for uneven sites. By setting up a detachable support leg 16, it can assist in connecting electrical equipment in a higher position and a narrow space, so as to facilitate the subsequent electrical test. When the support assembly is not needed to support the box body, in the default state, the support assembly is set in the placement slot 19, the fixing rod 12 is parallel to the steering rod 14, and the limiting rod 10 passes through the hinge seat 15, and the length direction of the limiting block 11 is perpendicular to the length direction of the limiting hole 17, so as to achieve the effect of fixing the hinge seat 15 (such as Figure 3 As shown); when the support is needed, pull the steering rod 14 to drive the second connecting rod 13 and the fixed rod 12 to rotate clockwise around the limit rod 10, and stop when the fixed rod 12 is perpendicular to the steering rod 14, that is, rotate the limit block 11 90° so that the limit block 11 corresponds to the limit hole 17 on the hinge seat 15, and then shrink under the action of the spring 9, and then rotate the support assembly so that the support assembly supports the box; if the steering rod 14 is pressed downward to limit the spring 9 from shrinking during the support, and then pull the steering rod 14 to drive the second connecting rod 13 and the fixed rod 12 to rotate clockwise around the limit rod 10, and stop when the fixed rod 12 is perpendicular to the steering rod 14, that is, rotate the limit block 11 90° so that the limit block 11 corresponds to the limit hole 17 on the hinge seat 15, and then shrink under the action of the spring 9, and then rotate the support assembly so that the support assembly supports the box; if the steering rod 14 is pressed downward to limit the spring 9 from shrinking, and then pull the steering rod 14 to drive the second connecting rod 1 3 and the fixing rod 12 rotate clockwise around the limiting rod 10, and stop when the fixing rod 12 is perpendicular to the steering rod 14, that is, the limiting block 11 is rotated 90°, so that the limiting block 11 corresponds to the limiting hole 17 on the hinge seat 15. At this time, the support assembly is rotated again, so that the support assembly can support the box body. At the same time, the limiting block 11 corresponds to the limiting hole 17, and the steering rod 14 is released. Under the pulling force of the spring 9, the limiting block 11 limits the support assembly to prevent the support assembly from moving, further improving the stability of the support assembly when supporting (such as Figure 2 as shown).

[0024] It should be noted that the supporting leg 16 is a telescopic rod.

[0025] like Figure 5 As shown, the electrical test module includes a voltage module, a current module, a partial discharge module 1, a partial discharge module 2, a temperature module, a pre-test module, a module to be tested and an alarm module. The electrical test module is electrically connected to the test instrument 23 and the alarm light 28 of the temperature sensor. The alarm module will give an alarm prompt when the test results of the pre-test module and the module to be tested are abnormal, and feedback the abnormal items of the results, so that the user can take targeted measures to improve the abnormal situation according to the abnormal situation.

[0026] Working principle: Step 1: The staff opens the box and selects the appropriate support method according to the needs.

[0027] Specifically, the staff carries the tester to the vicinity of the equipment to be tested for electricity by means of the handle 4, opens the box and fixes the box to the electrical equipment by means of the handle 4 as required, or pulls the steering rod 14, drives the connecting rod 2 13 and the fixing rod 12 to rotate around the limiting rod 10, rotates the limiting block 11 90° clockwise, so that the limiting block 11 corresponds to the limiting hole 17 on the hinge seat 15, contracts under the action of the spring 9, and then rotates the support assembly so that the support assembly supports the tester; or when supporting, presses the steering button downward. Rod 14 limits the contraction of spring 9, and then pulls the steering rod 14, driving the connecting rod 2 13 and the fixed rod 12 to rotate around the limit rod 10, and rotates the limit block 11 90° clockwise, so that the limit block 11 corresponds to the limit hole 17 on the hinge seat 15. At this time, rotate the support assembly again, so that the support assembly supports the box body, and the limit block 11 corresponds to the limit hole 17, loosens the steering rod 14, and under the pulling force of the spring 9, the limit block 11 limits the support assembly, thereby improving the stability of the support assembly during support.

[0028] Step 2: Use a connecting wire to connect the normally functioning electrical device to the connecting socket 24 of the corresponding test instrument 23 to perform a pre-test and calibrate the test assembly.

[0029] Specifically, the two ends of the connecting wire are respectively connected to the normally functioning electrical equipment and the connecting socket 24, and the normally functioning electrical equipment is subjected to an electrical inspection test. For special cases, such as when the connecting wire is too short or the test space is small, the test instrument 23 can be removed separately, and then the connecting wire is used to connect the normally functioning electrical equipment and the test instrument 23, or the normally functioning electrical equipment is directly tested to implement the electrical inspection test. At the same time, as needed, the connecting wire with the temperature sensor is respectively connected to the normally functioning electrical equipment and the corresponding connecting socket 24 to perform a temperature test.

[0030] In order to improve the accuracy of the test results, three groups of normally operating electrical equipment or power supply equipment connected to the electrical equipment to be tested are connected respectively. After the connection, the voltage module, the current module, the partial discharge module 1, the partial discharge module 2, and the temperature module obtain the test results, which are fed back to the pre-test module and displayed on the display screen 26, so that the staff can intuitively understand the current and voltage conditions of the normally operating electrical equipment or the power supply equipment to be tested. If a corresponding data in the three groups of data obtained shows obvious abnormalities at the same time, it may be caused by the tester not being calibrated or the internal connection being incorrect, and the tester needs to be calibrated; if a single data in one group of data shows obvious abnormalities, it is necessary to retest the data. If it is still abnormal after retesting, there is an abnormality inside the normally operating electrical equipment, but it does not affect its normal operation. After receiving the abnormal signal, the alarm module controls the corresponding alarm light 28 to light up and issue an alarm prompt, so that the staff can take corresponding measures, thereby discovering and solving the abnormal conditions of the normally operating electrical equipment or power supply equipment while pre-testing and calibrating the test components, ensuring that the electrical equipment to be tested will not be affected by external factors, which is conducive to improving the accuracy of the test results.

[0031] Step 3: Use a connecting wire to connect the electrical device to be tested and the connecting socket 24 of the corresponding test instrument 23 to perform a formal test.

[0032] Specifically, the two ends of the connecting wire are respectively connected to the electrical equipment to be tested and the connecting socket 24, and the electrical equipment to be tested is subjected to an electrical test. For special cases, such as when the connecting wire is too short or the test space is small, the test instrument 23 can be removed separately, and then connected to the electrical equipment to be tested and the test instrument 23 through the connecting wire or the electrical equipment is directly tested to achieve an electrical test. At the same time, as needed, the connecting wire with the temperature sensor is respectively connected to the electrical equipment to be tested and the corresponding connecting socket 24 to perform a temperature test. After the connection, the voltage module, the current module, the partial discharge module 1, the partial discharge module 2, and the temperature module obtain the test results, which are fed back to the module to be tested and displayed on the display screen 26 at the same time.

[0033] Step 4: The module to be tested makes judgment and analysis based on the test results, and feeds back abnormal data to the alarm module, and the corresponding alarm light 28 gives an alarm prompt.

[0034] Specifically, the voltage module, current module, partial discharge module 1, partial discharge module 2, and temperature module obtain test results. When the voltage, current, temperature is abnormal or partial discharge occurs, the control module receives a signal, controls the corresponding alarm light 28 to light up, and issues an alarm prompt. The staff conducts multi-point tests on the electrical equipment based on the prompts, and can further identify abnormal areas in the test results, so as to facilitate subsequent targeted maintenance of the abnormal areas and improve the efficiency of the test and the accuracy of the test results.
