Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of relay protection, and particularly relates to an anti-interference relay protection device. BACKGROUND

[0002] In power electronic components, the relay protection device plays a vital role, which can act quickly when the power system fails or abnormity occurs, and cut off the fault part to ensure the safe and stable operation of the power system.

[0003] When the relay protector detects a fault signal and judges that it needs to act, the internal relay contact will be closed, thereby controlling the opening and closing operation of the relay. However, the internal contact of the relay protector is prone to wear and tear during frequent operation. The wear and tear of the contact will cause the contact resistance to increase, resulting in poor contact, signal transmission interruption or miscommunication, affecting the reliability of the relay protector during operation. In addition, when a short circuit occurs in the circuit, a large current will be generated instantaneously. This short-circuit current may be far beyond the rated current carrying capacity of the contact. The strong current will generate a lot of heat in the contact area. The high temperature will cause the metal on the surface of the contact to melt rapidly, just like two pieces of metal are heated to a high temperature and fused together. When the short-circuit fault disappears and the current returns to normal, the already melted metal will stick together during the cooling process, causing the contact to fail to separate normally, affecting the normal operation of the relay protector, and greatly reducing the safety and reliability of the relay protector during use.

[0038] The operation principle of the present application is described as follows:

[0039] In the application, during the normal use of the relay protector 1, the anti-interference function of the relay protector 1 is realized by the anti-interference material of the shell of the relay protector 1, and every time after the internal contacts of the relay protector 1 are closed and then opened, the first sliding rail 31 is controlled to start, driving the first sliding plate 32 to move, so that the fixed frame 35 moves to the position right above the two contacts which are closed before, then the first electric telescopic rod 34 is controlled to start, driving the fixed frame 35 to move downward, when the contact surfaces of the two contacts are adhered together, at this time, the two contacts will block the insertion rod 62 as the fixed frame 35 drives the insertion

contacts in the relay protector 1 in time, when the two contacts below the fixed frame 35 are not adhered together, the fixed frame 35 is controlled to move to the side of the corresponding contact, because the transmission components, support components and the like connected with the contacts will be worn after long-term use, for example, the connecting rod connecting the contact and the operating mechanism will gradually thin due to friction, the gap will increase, when the contact operates, the movement accuracy of the connecting rod will decrease, and the operating force cannot be

corresponding second sliding plate 310 and the third sliding plate 312 to move, so that the detection plate 313 moves to different positions of the contact detection surface, then the second electric telescopic rod 38 is controlled to start, driving the detection plate 313 to move close to the surface of the contact, so that the detection rod 317 contacts the surface of the contact surface, as the detection rods 317 continuously move, the detection rods 317 will be blocked by the contact surface, at this time, the detection rods 317 will bring pressure to the first pressure sensor 315 through the detection spring 316, when the pressures detected by all the first pressure sensors 315 are the same, at this time, it indicates that there is no pit or uneven place at the position of the contact surface due to wear, when the pressures detected by the plurality of first pressure sensors 315 are different, it indicates that the position of the detection rod 317 contacting the contact surface has a pit or uneven place, so that the pressure value brought by the detection rod 317 to the first pressure sensor 315 through the detection spring 316 is different from other values, then the

motor 57 is controlled to start, the third round rod 56 is driven to rotate, the third round rod 56 drives the connecting rod 58 and the support plate 59 to rotate, after the inclination angle of the support plate 59 is same with the inclination angle of the back of the corresponding contact surface, the fifth motor 57 is controlled to close, then the fifth electric telescopic rod 54 is controlled to start, the support plate 59 is driven to move, the back of the contact is supported by the support plate 59, then the fourth slide rail 44 and the fifth slide rail 46 are controlled to start, the corresponding fourth slide plate 45 and the fifth slide plate 47 are driven to move, the position of the contact polishing plate 49 is controlled, the contact polishing plate 49 is moved to the side of the contact surface wear, then the third electric telescopic rod 43 is controlled to start, the contact polishing plate 49 is driven to move, the polishing surface of the contact polishing plate 49 is contacted with the wear position of the contact surface, then the fourth motor 48 is controlled to start, the contact polishing plate 49 is driven to rotate, the wear position of the contact surface is polished, the contact surface can be relatively smooth, which is convenient for continuous use, after the detection and polishing of the contact surface of the contact are completed, the above components continue to detect the wear of the contact surface of another contact, ensure that the contact surface of each contact meets the requirements, can detect the wear of the contact surface by the detection rod 317 during the normal use of the relay protector 1, after detecting the wear of the contact surface, the wear position of the contact surface is polished by the contact polishing plate 49, the contact surface is relatively smooth, which prevents the contact from being worn to increase the contact resistance, causes the contact to be poor, causes the signal transmission to be interrupted or mis-transmitted, and affects the reliability of the relay protector 1 during work, and during the detection and polishing of the contact surface, the inclination
