[0016] Compared with the prior art, the present invention provides a power capacitor fault detector having the following features:
[0017] Beneficial effects:
[0018] 1. Compared with the prior art, the present invention pushes two push plates on the same test connector to drive several limit shafts away from each other, so that the limit shafts are received in the limit box, the test connector is moved downward, so that the test connector is placed inside the test interface, and the push plate is released. Several limit shafts are pushed closer to each other through several reset springs, so that the limit shafts enter the corresponding limit holes in the test interface, so that the test connector and the test interface are fixed together. At this time, the test clamp is connected with the detector body, and the capacitance of the capacitor can be detected by clamping the test clamp on the wire of the capacitor. When the test clamp is used, the two push plates on the same test connector are pushed to drive several limit shafts away from each other, so that the limit shafts are separated from the test interface. At this time, the test connector can be separated from the test interface by moving the test connector upward, so that the test clamp can be removed, so that the test clamp is easy to disassemble and assemble. During the use of the test clamp, if the distance between the test clamp and the detector body is too large or too small, it will cause the wire to be entangled or the test clamp to be loose. When the clamp is inconvenient to use, the two handles in the same installation box are pushed, thereby driving the two clamps to move away from each other, so that the second wire loses its limit. At this time, the second wire is pulled to the left, so that the second wire is extended, thereby increasing the distance between the detector body and the test clamp, and the second wire is released. At this time, the tightened torsion spring rebounds and pulls the second wire into the storage box. At this time, the first wire is shortened, thereby shortening the distance between the detector body and the test clamp, and the handle is released. The two clamps are pushed closer to each other by the extrusion spring to squeeze the second wire, so that the second wire and the storage box are fixed together, thereby making it easy to adjust the distance between the detector body and the test clamp, so that the device is easy to quickly disassemble and assemble the test clamp, making the device more time-saving when used, and convenient for quickly extending and storing the wires between the test clamp and the detector body, convenient for adjusting the position of the test clamp, and not easy for the wires to be entangled, thereby improving the convenience of use of the device and improving user experience.
[0019] 2. Compared with the prior art, the present invention protects the jaws of the test pliers through a protective cover, and improves the sealing of the connection between the two protective covers through a sealing pad, so that dust is not easily attached to the surface of the jaws of the test pliers when placed. When the test pliers need to be used, the two handles of the test pliers are pressed to open the two jaws of the test pliers, thereby opening the two protective covers. When the jaws of the test pliers are located on the side of the capacitor wire, the handles are released to bring the two jaws of the test pliers closer to each other, thereby driving the two protective covers closer to each other. Since the connecting rod can slide in the protective cover, when the two protective covers contact the capacitor wire, the two protective covers are The protective cover will be limited, and the several connecting rods and the two jaws can continue to approach until the two jaws are in contact with the capacitor wire, so that the protective cover will not affect the normal use of the test clamp. When the test clamp is used, the test clamp is removed from the capacitor wire, and the two protective covers are pushed closer to each other through the connecting spring to automatically seal the jaws of the test clamp. This makes it easy to improve the dust-proof ability of the test clamp when it is placed without affecting the forward movement of the normal use of the test clamp, so that the sensitivity of the jaws of the test clamp is not easy to decrease, which is convenient to improve the accuracy of the detection results of the detector main body, thereby improving the detection accuracy of the device.

[0035] During specific implementation: when it is necessary to detect whether the capacitance of the capacitor meets the standard, rotate the sealing cover 39 to open the detector body 1, connect the power line through the power interface 31, push the two push plates 10 on the same test connector 4, thereby driving the two push plates 10 away from each other, thereby driving the two positioning seats 9 away from each other, thereby driving the two placement plates 7 away from each other, thereby driving the plurality of limit shafts 8 away from each other, so that the limit shafts 8 are received in the limit box 6, move the test connector 4 downward, so that the test connector 4 is placed in the test interface 3, and limit the test connector 4 through the slider 13 to avoid position deviation when the test connector 4 is connected to the test interface 3. When the test connector 4 is connected to the test interface 3, release the push plate 10, and at this time, through the plurality of reset springs 1 2 pushes the two placement plates 7 to approach each other, thereby driving the plurality of limit shafts 8 to approach each other, so that the limit shafts 8 enter the corresponding limit holes in the test interface 3, so that the test connector 4 and the test interface 3 are fixed together.

The capacitance information is displayed on the display screen of the detector body 1, so that it can be judged whether the capacitance of the capacitor meets the standard. When the test clamp 30 is used, the two push plates 10 on the same test connector 4 are pushed, so that the two push plates 10 are driven away from each other, thereby driving the two positioning seats 9 away from each other, thereby driving the two placement plates 7 away from each other, thereby driving the plurality of limit shafts 8 away from each other, so that the limit shafts 8 When the test clamp 30 is used, if the distance between the test clamp 30 and the detector body 1 is too large or too small, resulting in the entanglement of the wires or the inconvenience of using the test clamp 30, the two handles 23 in the same installation box 21 are pushed, thereby driving the two handles 23 away from each other, thereby driving the two clamps 22 away from each other, so that the second wire 19 loses its limit, and the second wire 19 is pulled to the left at this time, so that the second wire 19 is pulled out of the storage box 15, and the torsion spring 17 is gradually tightened by the second wire 19, and the first wire 14, the second wire 19, and the third wire 27 are connected to the tester body 1.

[0036] Embodiment 2:
[0037] See also Figure 1-Figure 8 A plurality of connecting rods 34 are fixedly provided on the sides of the two test clamps 30 , and a connecting plate 35 is fixedly provided at one end of the plurality of connecting rods 34 , and the connecting plate 35 is convenient for fixing the connecting spring 36 .
[0038] As a further implementation scheme of the above technical scheme: a connection spring 36 is fixedly provided on one side of the plurality of connection plates 35 , and four protective sleeves 37 are provided between the plurality of connection springs 36 , so that the connection springs 36 are convenient for squeezing the protective sleeves 37 .
[0039] As a further implementation scheme of the above technical scheme: the outer sides of the four protective sleeves 37 are respectively fixedly connected to one side of a plurality of connecting springs 36 , and the inner sides of the four protective sleeves 37 are fixedly provided with sealing pads 38 , so that the protective sleeves 37 are convenient for protecting the jaws of the test pliers 30 .
[0040] As a further implementation scheme of the above technical scheme: a plurality of sealing holes are opened inside the four protective sleeves 37 , and the interiors of the plurality of sealing holes are respectively fitted with the side surfaces of a plurality of connecting rods 34 , and the connecting rods 34 are convenient for fixing the connecting disk 35 .
[0041] As a further implementation scheme of the above technical scheme: the four sealing gaskets 38 are divided into two groups, one side of the two sealing gaskets 38 in one group is respectively fitted with one side of the two sealing gaskets 38 in another group, so that the sealing gaskets 38 can improve the sealing performance of the connection between the two protective sleeves 37.
[0042] During specific implementation: the jaws of the test clamp 30 are used to connect with the capacitor wire to facilitate the detection of the capacitance of the capacitor. However, dust and other impurities are easily attached to the surface of the jaws of the test clamp 30 when not in use, which makes the sensitivity of the jaws of the test clamp 30 gradually decrease, which can easily lead to poor contact between the jaws of the test clamp 30 and the capacitor wire, resulting in inaccurate detection results of the detector main body 1, thereby reducing the detection accuracy of the device. When the device is in use, when the test clamp 30 is not in use, the jaws of the test clamp 30 are protected by two protective covers 37 on the same test clamp 30, and the sealing of the connection between the two protective covers 37 is improved by the sealing gasket 38, so that dust is not easily attached to the surface of the jaws of the test clamp 30 when it is placed. When the test clamp 30 needs to be used, the two handles of the test clamp 30 are pressed to open the two jaws of the test clamp 30, thereby opening the two protective covers 37. When the jaws of the test clamp 30 are located on the side of the capacitor wire, When the test clamp 30 is used, the handle is released so that the two jaws of the test clamp 30 are close to each other, thereby driving the two protective covers 37 to be close to each other. Since the connecting rod 34 can slide in the protective cover 37, when the two protective covers 37 contact the capacitor wire, the two protective covers 37 will be limited, and the connecting rods 34 and the two jaws can continue to be close until the two jaws are in contact with the capacitor wire, so that the protective cover 37 will not affect the normal use of the test clamp 30. When the test clamp 30 is used, the test clamp 30 is removed from the capacitor wire, and the two protective covers 37 are pushed close to each other by the connecting spring 36 to automatically seal the jaws of the test clamp 30, so that the device can improve the dustproof ability of the test clamp 30 when it is placed without affecting the normal use of the test clamp 30. The sensitivity of the jaws of the test clamp 30 is not easy to decrease, which is convenient for improving the accuracy of the detection result of the detector main body 1, thereby improving the detection accuracy of the device.
