Description

Technical Field

[0001] This invention relates to the field of bypass switches, and in particular to a bypass switch withstand voltage detection system. Background Technology

[0002] A bypass switch is a common low-voltage electrical appliance, often used in important power distribution applications (such as data centers) for switching between two power sources. It ensures that when the main power source fails during power supply, the system can quickly switch to the backup power source to ensure normal power supply to the load. At the same time, it ensures that the bypass switch supplies power to important loads during the inspection and maintenance of the switch itself, enabling uninterrupted maintenance.

[0003] Due to the specific application scenarios of bypass switches, after the bypass switches are manufactured, their withstand voltage and other performance characteristics need to be tested to ensure they pass the tests before being put into use. Traditional testing methods involve manually using a withstand voltage tester to sequentially test the bypass switches to ensure excellent withstand voltage performance. In addition to using the withstand voltage tester, the bypass switches also need to be manually operated to ensure they can still open and close under pressure. However, when the bypass switch is not connected to the power distribution system, manual operation is required to test its operation. A person holds a lever, inserts it into the switch's opening and closing ports, and moves the lever to open or close the switch. This process requires multiple manual operations to perform multiple opening and closing tests, which is very cumbersome, labor-intensive, and only allows testing of one bypass switch at a time, resulting in low testing efficiency.

[0038] The following examples can make the skilled in the art more fully understand the present application, but the present application is not limited in the scope of the described examples.

[0039] As shown in Figures 1-14 a bypass switch voltage withstand detection system, comprising a voltage withstand detection support 5, a voltage withstand detection push plate 501, a voltage withstand test assembly.

The pressure resistance test columns 503 and the pressure resistance test base plates 502 are further connected with a pair of first pressure resistance reinforcing plates 505 to strengthen the stability of the connection between the pressure resistance test columns 503 and the pressure resistance test base plates 502. The pressure resistance test beams 504 are connected to the top ends of the pressure resistance test columns 503. The pressure resistance test beams 504, the pressure resistance test columns 503 and the pressure resistance test base plates 502 are further connected with a pair of second pressure resistance reinforcing plates 506 to strengthen the structural stability between the pressure resistance test beams 504, the pressure resistance test columns 503 and the pressure resistance test base plates 502, thereby ensuring the structural strength of the pressure resistance detection support 5 as a whole.

[0041] The pressure resistance detection push plate 501 is driven by a first lifting mechanism installed on the pressure resistance detection support 5 to move up and down. The first lifting mechanism comprises first lifting rails 507 vertically arranged on the pressure resistance test columns 503, first lifting sliders 508 installed on the two sides of the pressure resistance detection push plate 501 and matched with the first lifting rails 507, and a first lifting cylinder 509 installed on the pressure resistance test beam 504. The piston rod of the first lifting cylinder 509 is connected to the pressure resistance detection push plate 501 and drives the pressure resistance detection push plate 501 to move up and down along the third lifting rail 507.

[0042] The pressure resistance test assembly is several and horizontally arranged in parallel on the pressure resistance detection push plate 501. The pressure resistance test assembly comprises first pressure resistance contacts 510, a lever 511, a contact mounting plate 518, a spring pressure head 521 and a pressure resistance measuring head 514.

[0043] The first pressure resistance contacts 510 are two and arranged in parallel on the pressure resistance detection push plate 501. The pressure resistance detection push plate 501 is further provided with through holes for mounting and moving the first pressure resistance contacts 510. The first pressure resistance contacts 510 are driven by a second lifting mechanism to move up and down.

[0044] As Figures 10-12As shown, the second lifting mechanism is that two first pressure contact heads 510 are respectively installed on the pressure detection push plate 501 through a contact head pressing rod 530, a through hole is opened on the contact head pressing rod 530 for the first pressure contact head 510 to pass through, a limiting ring 512 is further connected to the middle position of the first pressure contact head 510, the size of the limiting ring 512 is larger than the size of the through hole on the contact head pressing rod 530, the top end of the first pressure contact head 510 extends out of the upper end surface of the first pressure contact head 510 after passing through the through hole on the first pressure contact head 510, and the top end of the first pressure contact head 510 is locked through a nut, the top end of the first pressure contact head 510 is matched with the external thread structure of the nut, and the connection and fixation between the first pressure contact head 510 and the contact head pressing rod 530 are realized through the cooperation of the limiting ring 512 and the nut. With this structure, the first pressure contact head 510 can be detachably connected, which facilitates the installation of the first pressure contact head 510 and also facilitates the subsequent disassembly, replacement and maintenance of the first pressure contact head 510.

The second lifting cylinder 514 is a gas cylinder. Through the cooperation of the contact head pressing rod 530, the installation rod 513 and the second lifting cylinder 514, the first pressure contact head 510 is realized to ascend and descend by swinging. During the pressure test, under the same force requirement applied to the first pressure contact head 510, compared with directly using a driving cylinder to drive the first pressure contact head 510, the principle of lever is used to apply force, the requirement for the force applied to the second lifting cylinder 514 is greatly reduced, that is, the requirement for the second lifting cylinder 514 is reduced, and the corresponding test cost is also reduced.
