Abstract
Description

[0002] The instrument transformer, also known as the instrument transformer, is a general term for current transformers and voltage transformers. It is a primary device that realizes the communication between the primary and secondary electrical systems. In order to understand the usage data of the instrument transformer, it is necessary to test the working data of the instrument transformer through a tester.
[0003] Existing transformer testers are generally composed of an aluminum alloy shell and electrical components arranged inside the aluminum alloy shell. During testing, the transformer to be tested is generally placed next to the tester, and then the connecting wires are respectively connected to the terminals on the transformer tester and the corresponding terminals on the transformer, and then the power is turned on for testing. However, when the transformer is pressure tested, since the voltage of the detection alternating current is continuously increased during the detection process to detect the pressure of the transformer, the transformer is prone to leakage under extreme conditions, which may cause the staff to be easily shocked. In addition, the transformer is prone to spontaneous combustion or explosion during extreme testing. Since there is no shielding between the staff and the transformer, it may cause injuries to the staff. For this reason, we propose a transformer pressure tester. Utility Model Content

DETAILED DESCRIPTION
[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] See also Figures 1 to 3 The utility model provides a technical solution: a transformer pressure tester, including a test platform 1, a storage platform 9 is provided at one end of the top of the test platform 1, the bottom of the storage platform 9 is fixed on the storage platform 9 through a plurality of first support columns 11, an insulating pad 21 is installed on the top of the storage platform 9, a transformer is placed on the top of the insulating pad 21, and the outer surface of the first support column 11 is wrapped with insulating rubber or insulating plastic. In this way, the transformer and the test platform 1 can be insulated under the action of the insulating pad 21 and the first support column 11, so as to prevent the current passed into the transformer from being transmitted to the test platform 1 during the test, and to prevent the staff from being shocked.
[0021] like Figure 2 As shown, mounting seats 6 are vertically installed on both sides of the top of the storage platform 9, and telescopic mechanisms 8 are installed on the sides of the mounting seats 6. Two clamping plates 5 are symmetrically arranged between the two mounting seats 6, and the clamping plates 5 are respectively located on both sides of the mutual inductor, and the sides of the clamping plates 5 that are away from each other are respectively fixed to the corresponding ends of the telescopic mechanisms 8. The telescopic mechanism 8 is a kind of cylinder or hydraulic cylinder, and the clamping plates 5 can be pushed by the telescopic mechanism 8 to fix the mutual inductor, which is convenient for fixing.
[0022] It should be noted that the adjacent surfaces of the two clamps 5 are both arc-shaped structures, and the surface of the clamp 5 is wrapped with a layer of insulating rubber. Since the mutual inductor is generally ring-shaped, when the mutual inductor is clamped, the contact area between the clamp 5 and the mutual inductor can be increased, the stability of the clamping is improved, and when the mutual inductor leaks, the current will not be transmitted along the clamp 5.
[0023] like Figure 2As shown, at least one guide rod 7 is vertically installed on one side of each splint 5 close to the mounting seat 6, and the other end of each guide rod 7 slides through the mounting seat 6. The splint 5 can be limited by the guide rod 7, and the stability of the splint 5 can be guaranteed when clamping.
[0024] like Figure 1 As shown, a plurality of supporting legs 12 are installed around the bottom of the test bench 1, a bottom plate 20 is installed between the supporting legs 12, a control box 19 is installed on the top of the bottom plate 20, a mounting plate 14 is provided inside the control box 19, the bottom of the mounting plate 14 is fixed to the inner bottom end of the control box 19 through a plurality of second supporting columns 16, a voltage regulator 13, a voltage detector 23 and a current detector 24 are installed on the top of the mounting plate 14, the wiring terminals of the voltage regulator 13, the voltage detector 23 and the current detector 24 are all connected with wires 10, the wires 10 are connected to the mutual inductor, and the other ends of the wires 10 respectively penetrate the control box 1 9 and a test bench 1, the end of the wire 10 is connected with a terminal head 22 matching the transformer terminal, the terminal head 22 is installed on the transformer terminal, a controller 15 is installed on the top of the mounting plate 14, the controller 15 is a host or a control mainboard, a display 2 is installed on the top of the test bench 1, the controller 15 is respectively connected to the voltage regulator 13, the voltage detector 23 and the current detector 24 and the display 2 through data lines, the controller 15 is connected to the AC power supply through a power line, and during use, the voltage detector 23 and the current detector 24 detect the voltage and current after the transformer is powered on.
[0025] Specifically, during the actual use of the utility model, the staff places the mutual inductor to be tested on the storage table 9, and then controls the telescopic mechanism 8 to extend, and the telescopic mechanism 8 pushes the two clamps 5 to move relative to each other, clamping and fixing the mutual inductor, and then puts the terminal 22 on the terminal of the mutual inductor, and then transmits the alternating current to the mutual inductor after the voltage is adjusted by the voltage regulator 13 through the controller 15. The detection voltage can be continuously increased through the voltage regulator 13, and the mutual inductor can be pressure-tested through the voltage detector 23 and the current detector 24, and the controller 15 transmits the detection data to the display 2 for display, so that the staff can observe.
[0026] It should be noted that the outer surface of the second support column 16 is wrapped with insulating rubber or insulating plastic, so that the mounting plate 14 and the control box 19 can be insulated to prevent the current in the controller 15 and the voltage regulator 13 from being introduced into the housing of the control box 19, so as to avoid electric shock to the staff during inspection.
[0027] Further, such as Figure 1As shown, a protective plate 3 is provided between the storage table 9 and the display 2, the bottom of the protective plate 3 is fixed on the test table 1, and an observation window 4 is provided on the side of the protective plate 3. The observation window 4 is a glass observation window, through which the display 2 and the transformer to be tested can be separated, so that during the process of pressure testing of the transformer, when the transformer spontaneously ignites or explodes, it will not cause harm to the staff, and during the testing process, the staff can observe the appearance of the transformer to be tested through the observation window 4.
[0028] Further, such as Figure 3 As shown, a protective cover 17 is provided on one side of the top of the test bench 1 near the storage platform 9, the storage platform 9 is located inside the protective cover 17, one side of the protective cover 17 is fixed on the protective plate 3, and both sides of the opening of the protective cover 17 are connected with protective doors 18 through hinges, and the protective doors 18 cover the opening of the protective cover 17. The protective door 18 can be closed after the transformer to be tested is installed and connected to the voltage regulator 13, so that the transformer to be tested is in a sealed space, so that in the event of an accident, it will not cause damage to the surrounding environment.
[0029] It should be noted that the connection parts between the wire 10 and the test bench 1 and the control box 19 are all covered with insulating sleeves, so that the surface of the wire 10 will not be worn and leak electricity during the movement.
