Description

Technical Field

[0001] The utility model relates to the technical field of power frequency probes, in particular to a power frequency probe fixing bracket. Background Art

[0002] With the development of energy storage technology, the integration and space utilization of energy storage systems are constantly improving, and the spacing between devices is constantly compressed during design, resulting in a harsh and complex electromagnetic field environment in the energy storage system. During the debugging and testing phase of the energy storage system, false alarms of equipment being affected by electromagnetic interference will frequently occur due to unreasonable layout. Therefore, it is necessary to analyze the electromagnetic interference of the on-site environment, identify the interference sources of electromagnetic radiation and the susceptible devices of the susceptible devices, and take certain shielding measures for the interference sources or susceptible devices, or optimize their system layout. During the test, the probe needs to be directly in contact with the test point, but the devices and wiring in the energy storage system are relatively complex, and there may be no horizontal plane at the test point to place the power frequency probe. The power frequency probe needs to be fixed with the help of an external structure.

[0003] There are two existing probe fixing methods: one method is that the operator directly holds the probe to test the test point, but the manual holding is easy to shake and move during the test, which causes abnormal fluctuations in the test value, and this method cannot close the door when the point is in the energy storage system equipment compartment or battery compartment, and the electromagnetic field will leak out during the test and cause the test value to be lower than the actual value; the other method is to use tape to fix the probe. This method makes the stability and space tightness of the probe basically meet the requirements, but the probe is subjected to force by the tape, and the risk of falling is high. In addition, the tape is easy to deform under the action of the gravity of the probe, resulting in an increase in the gap between the power frequency probe and the contact surface of the test point, thereby affecting the test value of the probe. In addition, the tape fixation takes a long time and consumes a lot of tape resources. As a test instrument with a higher resolution, if the probe shell is covered with foreign objects, a certain electromagnetic field reflection will be generated and numerical errors will be caused. Therefore, neither of the two existing probe fixing methods can fully meet the test requirements. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a power frequency probe fixing bracket to solve the problems of poor stability and large test value error in the existing probe fixing method.

[0006] Furthermore, gaskets are provided on both the first clamping plate and the second clamping plate.

[0007] Furthermore, the clamping plate assembly also includes a fastening bolt, a bolt hole is opened on the first clamping plate, and the fastening bolt is arranged in the bolt hole.

[0008] Furthermore, the fastening bolt is provided with a hand-tightening portion.

[0009] Furthermore, the flexible bracket is provided with a fixing portion near the second clamping plate, the outer wall of the fixing portion is provided with the external thread, the outer contour of the cross section of the fixing portion perpendicular to its length direction is oval, and the through hole is an oval through hole.

During the fixing process, the operator can plasticize the flexible bracket 1 so that the industrial frequency probe 4 is fixed at the test point, and then the test is carried out.

[0030] From the above description, it can be seen that the beneficial effects of the utility model are: the industrial frequency probe fixing bracket described in the utility model can effectively ensure the stability of the probe and reduce the risk of the probe falling. The industrial frequency probe fixing bracket has high reliability. When testing points in the energy storage system equipment compartment or battery compartment, the industrial frequency probe fixing bracket can ensure the spatial airtightness of the energy storage system equipment compartment or battery compartment; in addition, using the industrial frequency probe fixing bracket to fix the industrial frequency probe 4 can avoid foreign matter covering the probe shell, and the industrial frequency probe fixing bracket can improve the efficiency of fixed-point fixation of the industrial frequency probe 4, and improve the precision and accuracy of the electromagnetic field value tested by the industrial frequency probe 4.

[0031] Furthermore, a gasket 24 is disposed on both the first clamping plate 21 and the second clamping plate 22 .

[0032] It can be known from the above description that when the first clamping plate 21 and the second clamping plate 22 are clamped together, the gasket 24 can increase the friction between the first clamping plate 21 and the second clamping plate 22 to improve the stability and reliability of the clamp assembly.

[0033] Furthermore, the clamping plate assembly 2 also includes a fastening bolt 25. A bolt hole is opened on the first clamping plate 21, and the fastening bolt 25 is arranged in the bolt hole.

[0034] It can be seen from the above description that the locking and fixing ability of the clamp assembly can be further improved by tightening the bolts 25, thereby reducing the risk of displacement and falling off of the power frequency probe fixing bracket during the test process.

[0035] Furthermore, the fastening bolt 25 is provided with a hand-tightening portion 251 .

[0036] It can be seen from the above description that the operator can directly control the tightening of the fastening bolt 25 by hand, which is convenient and quick to operate.

[0042] Furthermore, the connecting bolt 31 is a polymer plastic bolt, and the socket 41 is a polymer plastic socket 41.

[0043] From the above description, it can be seen that because the electromagnetic field is transmitted outward in the form of waves, the electromagnetic field is essentially the vector superposition of the electric field and the magnetic field, the directions of the two are perpendicular to each other and at the same time perpendicular to the propagation direction. The polymer plastic bolt and the polymer plastic socket 41 can avoid electromagnetic conduction and improve the accuracy of the detection value of the power frequency probe 4.

[0044] Furthermore, the connection assembly 3 further includes a buffer member 32 , and the buffer member 32 is sleeved on one end of the connection bolt 31 close to the flexible bracket 1 .
