Description

Technical Field

[0001] The utility model belongs to the technical field of wireless vector testers, and in particular relates to a portable wireless vector tester for a substation. Background Art

[0002] When new equipment is put into operation in a substation or power is restored to equipment with modified secondary current circuits, a load vector test is required. This test measures the effective value of the three-phase load current and the phase relative to the reference voltage and determines the phase sequence to detect the correctness of the secondary current and voltage circuits, thereby ensuring correct protection operation.

[0003] In the test of conventional substation;

[0004] As shown in the reference case "A Wireless Load Vector Tester for Power Measurement" with announcement number "CN208421081U", this is a convenient and fast handheld instrument suitable for smart substations that can measure the amplitude and phase of signals between multiple locations, perform load vector testing, and directly display hexagonal diagrams.

[0005] In practice, existing wireless vector measurement systems often require operators to hold the instrument and constantly adjust its position and pitch to accurately search for a signal. Once a signal is found, the operator must maintain the instrument in a fixed position. However, maintaining this position for extended periods of time is laborious and prone to hand shake, which in turn affects test stability and accuracy. Utility Model Content

The connecting block 324 is located on one side of the installation component 33. When in use, the rotating block 323 can be rotated to quickly adjust the pitch angle of the vector tester 1, so as to quickly and conveniently search the voltage and capacitance signals of the substation, thereby improving the convenience of use of the vector tester 1. The adjustment component 32 also includes a support rod 325 fixedly installed on the surface of the fixed block 322, and a plurality of clamping blocks 326 are fixedly installed on the surface of the support rod 325. The rotating block 323 is clamped with the plurality of clamping blocks 326. The clamping blocks 326 are made of rubber. When the rotating block 323 rotates, it moves between the plurality of clamping blocks 326, and the rubber clamping blocks 326 can provide appropriate The friction and buffering effect enable the rotating block 323 to remain stable during rotation and avoid excessive sliding. At the same time, the elasticity of the rubber can effectively absorb tiny vibrations, further improving the stability of the vector tester 1 during signal search. When adjusting the pitch angle of the vector tester 1, the rotating block 323 can be accurately positioned, and after the adjustment is completed, it is automatically clamped between the clamping blocks 326 to prevent angle deviation due to vibration or accidental touch during operation. A connecting groove 327 is provided at the bottom of the support plate 321, and a drive disk 328 is rotatably installed at the top of the support rod 31.

The rubber block 335 is set to a semicircular shape, and multiple anti-slip strips 336 are fixedly installed on the surface of the support rod 31. The semicircular rubber block 335 design increases the contact area with the vector tester 1, so that the splint 333 can distribute the pressure more evenly when clamping, provide a more firm and stable fixing effect, and reduce the possibility of equipment displacement. The anti-slip strip 336 on the support rod 31 provides additional gripping friction to prevent the operator's hand from sliding when adjusting the angle or position of the tester, ensuring the stability of the support rod 31 during the test.

When the rotating block 323 rotates, it moves between multiple clamping blocks 326. The rubber clamping blocks 326 can provide appropriate friction and buffering effects, so that the rotating block 323 can remain stable during rotation to avoid excessive sliding. At the same time, the elasticity of the rubber can also effectively absorb small vibrations, further improving the stability of the vector tester 1 during signal search. When adjusting the pitch angle of the vector tester 1, the rotating block 323 can be accurately positioned, and after the adjustment is completed, it is automatically clamped between the clamping blocks 326 to prevent angle deviation due to vibration or accidental touch during operation. When the vector tester 1 needs to be adjusted When rotating, the driving disk 328 can be rotated to synchronously drive the support plate 321 to rotate, so that the operator can easily adjust the direction of the vector tester 1, so as to more conveniently align the target area of the substation for signal search and measurement.
