Description

Technical Field

[0001] The present invention relates to the technical field of relay protection testing, and in particular to relay protection testing equipment for an intelligent substation. Background Art

[0002] Relay protection test is a very important link in the power system. It aims to verify whether the function of the relay protection device is normal and ensure that when a fault occurs in the power system, the relay protection device can quickly and accurately cut off the fault and ensure the safe and stable operation of the power system.

[0003] Before the relay protection device leaves the factory, in order to ensure the function and stability of the relay protection device, it is generally necessary to conduct strict tests on each energized connection component of the relay protection device. Generally, the following aspects are tested: appearance inspection, resistance test, power supply impact test, etc., so as to test the working performance of the components of the relay protection device under different power supply conditions.

[0004] At present, the test of each energized connection component of the relay protection device, in addition to the electrical performance test, is also subject to an appearance inspection to ensure the integrity of the component. When faced with a large number of electrical component tests and inspections, they are generally completed on the operating table. In this process, due to the need to conduct a large number of electrical tests, the electrical components need to be insulated and locked during the test process to facilitate subsequent power-on testing. However, the insulation placement and locking structures of existing relay protection test equipment are mostly separated. In actual operation, the insulation placement and locking need to be completed separately. When the components are transferred for other tests, the insulation placement and locking need to be unlocked again, which reduces the efficiency of the test.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Reference Figure 1-9, a smart substation relay protection test equipment, in order to be able to form a clamping position for the electrical components while insulating and placing the electrical components, to help the electrical components quickly enter the state to be tested, to increase efficiency, and to facilitate and quickly test a large number of electrical components, the equipment includes an operating table 1, a test mechanism 2 for electrical testing is arranged on both sides above the operating table 1, a sliding track 3 for guiding the movement of the electrical components is arranged on the operating table 1, and a scanning mechanism 4 for appearance inspection is arranged above the sliding track 3; The opposite positioning mechanism 5 includes a driving assembly 51 and an opposite positioning assembly 52. ​​The opposite positioning assembly 52 includes a linkage frame 521, an extrusion frame 522 and a positioning extrusion block 523. The two extrusion frames 522 are mirror-symmetrical as a group, and the extrusion frames 522 are horizontally slidably installed on the side wall of the sliding track 3. The two linkage frames 521 are mirror-symmetrical as a group and are distributed below the two sides of the sliding track 3. One end of the linkage frame 521 is rotatably connected to the output end of the driving assembly 51, and the other end is rotatably connected to the extrusion frame 523. 2 is away from one end of the sliding track 3, so that the driving end of the driving assembly 51 can drive the two linkage frames 521 to move upward and squeeze the two extrusion frames 522 to slide towards each other on the two side walls of the sliding track 3, and the positioning extrusion blocks 523 are arranged at the ends of the extrusion frames 522, so that when the two extrusion frames 522 move towards each other, the positioning extrusion blocks 523 at the ends of the two extrusion frames 522 are close to each other on the inner side of the sliding track 3, and when the electrical component moves on the sliding track 3, the opposite extrusion positioning can be completed by the two oppositely moving extrusion frames 522; The component lifting mechanism 6 includes a lifting base frame 61 and a synchronous lifting assembly 62. The bottom wall of the sliding track 3 is provided with a groove. The lifting base frame 61 includes a lifting block frame 611 and a movable plug frame 612. The movable plug frame 612 is vertically penetrated and arranged on the bottom wall of the sliding track 3. The lifting block frame 611 is arranged in affixed to the groove of the bottom wall of the sliding track 3, and the top surface of the lifting block frame 611 is flush with the bottom wall of the sliding track 3. The lifting block frame 611 is an insulating ceramic block frame. The movable plug frame 612 passes through the frame body of the bottom wall of the sliding track 3 and is connected to the lifting block frame 611. The synchronous lifting assembly 62 is arranged between the driving assembly 51 and the sliding track 3. In between, the synchronous lifting component 62 acts on the movable rack 612, so that when the driving component 51 drives the two linkage racks 521 to move up, it can synchronously drive the movable rack 612 to move up, and can make the two extrusion racks 522 slide towards each other on the two side walls of the sliding track 3. The movable rack 612 and the lifting block rack 611 can be synchronously driven to move up, which helps to lift the electrical components to be tested in the sliding track 3. The lifting block rack 611 of insulating ceramic can play an insulating effect on the electrical components to be tested, thereby quickly completing the process of lifting insulation and opposite extrusion positioning for the electrical components, allowing the electrical components to quickly enter the state to be tested.

[0019] The driving assembly 51 includes a driving cylinder 511, a driving shaft 512 and a guiding mechanism 7. The driving cylinder 511 is vertically arranged below the operating table 1. The driving shaft 512 is arranged on the output end of the driving cylinder 511, and the driving shaft 512 is opposite to the bottom surface of the operating table 1. The linkage frame 521 is connected to the driving shaft 512. The guiding mechanism 7 is arranged on the bottom surface of the operating table 1, and the guiding mechanism 7 acts on the linkage frame 521.

[0020] The guide mechanism 7 includes a guide rail 701 and a limit groove 702. The two guide rails 701 are set in a mirror-symmetrical manner on the bottom wall of the operating table 1, and the opposite side walls of the two guide rails 701 are provided with guide grooves. The limit grooves 702 are provided on the inner walls of the guide grooves. The linkage frame 521 includes a connecting frame and a sliding block. The sliding block is arranged in contact with the guide groove of the guide rail 701. The upper and lower ends of the sliding block are provided with connecting frames, and one end of the connecting frame located below the sliding block is rotatably connected to the driving shaft 512, and the other end is rotatably connected to the sliding block. The connecting frame located above the sliding block is rotatably connected to the extrusion frame 522 at one end, and the other end is rotatably connected to the sliding block. Figure 8 As shown, when the driving shaft 512 rises, it can squeeze the sliding block to slide up in the guide groove of the guide track 701, and at the same time push the squeezing frame 522 to move horizontally on the side wall of the sliding track 3 through the connecting frame; Among them, protrusions are arranged on both sides of the sliding block, and the protrusions are arranged in contact with the limiting grooves 702. The limiting grooves 702 restrict the protrusions, so as to guide and restrict the sliding of the sliding block in the guide track 701.

[0021] The synchronous lifting assembly 62 includes a telescopic push rod 621 and a return spring 622. The telescopic push rod 621 is arranged at the end of the driving shaft 512, and the top of the telescopic push rod 621 is directly opposite to the movable plug-in bracket 612. The telescopic push rod 621 includes two rod bodies, one of which is fixedly arranged at the end of the driving shaft 512, and the other end of the rod body is slidably inserted at the end of the fixed rod body. The return spring 622 is arranged between the two rod bodies of the telescopic push rod 621, so that when the two rod bodies of the telescopic push rod 621 are shortened, the return spring 622 will be compressed, and the telescopic push rod 621 can maintain the recovery tendency. When the driving cylinder 511 drives the driving shaft 512 to rise, the telescopic push rod 621 rises synchronously and squeezes the bottom end of the movable rack 612, and the telescopic push rod 621 pushes the movable rack 612 to move upward. When the movable rack 612 rises and squeezes the bottom wall of the sliding track 3, the driving shaft 512 continues to rise, and the telescopic push rod 621 will shorten, squeezing the return spring 622 to compress. When the driving cylinder 511 drives the driving shaft 512 to descend, the telescopic push rod 621 descends. At this time, under the reverse action of the return spring 622, the telescopic push rod 621 will restore its original length; Through a driving cylinder 511 and a driving shaft 512, the telescopic push rod 621 is driven to rise and squeeze the jacking block frame 611 and the movable plug-in frame 612 to rise. At the same time, through the linkage effect of the linkage frame 521, the two squeezing frames 522 are synchronously driven to move toward each other on the two side walls of the sliding track 3. The positioning squeezing blocks 523 are used to clamp the electrical components for jacking in opposite directions, thereby quickly completing the effect of first lifting and then positioning in opposite directions, thereby increasing efficiency.

[0022] like Figure 3 and Figure 4 As shown, the positioning extrusion block 523 is a trapezoidal block made of insulating ceramic material, and the positioning extrusion blocks 523 at the ends of the two extrusion frames 522 are mirror-symmetrical, and the groove on the bottom wall of the sliding track 3 and the component lifting mechanism 6 are both located between the positioning extrusion blocks 523, as shown in FIG. Figure 3 As shown, the lifting block frame 611 is evenly distributed in the groove of the bottom wall of the sliding track 3, and the length of the lifting block frame 611 is greater than the length of the positioning extrusion block 523, so that the lifting range of the lifting block frame 611 is larger than the clamping range of the positioning extrusion block 523, and can adapt to the lifting and clamping of various long-length electrical components. The narrow side of the positioning extrusion block 523 is directly opposite, and a tooth block is provided on the narrow side of the positioning extrusion block 523, which can increase the clamping force when clamping the electrical component. The positioning extrusion block 523 and the bottom wall of the sliding track 3 are There is a gap between the two components, and the height of the gap is the same as the lifting height of the lifting block frame 611, so that after the lifting block frame 611 of the component lifting mechanism 6 lifts the long-length electrical component, the positioning extrusion block 523 can clamp the two sides of the electrical component to keep the long-length electrical component in the middle position above the lifting block frame 611. At the same time, it can also form a clamping and positioning for the long-length electrical component to prevent the long-length electrical component from tilting on the lifting block frame 611 and causing the two ends to contact the bottom wall of the sliding track 3 and destroy the insulation.

[0023] like Figure 3 and Figure 4 As shown, the two positioning extrusion blocks 523 form a channel on the inner side of the sliding track 3 that is wide on both sides and narrow in the middle, so that when the long-length electrical component moves forward on the sliding track 3 and passes between the two positioning extrusion blocks 523, the channel that becomes narrower from wide can guide the electrical component to move to the middle part of the two positioning extrusion blocks 523. At this time, the middle part of the long-length electrical component will be located on the lifting block frame 611, which is convenient for subsequent lifting and opposite clamping positioning.

[0024] An extrusion spring 8 is arranged between the extrusion frame 522 and the side wall of the sliding track 3, and the extrusion spring 8 is arranged around the outside of the extrusion frame 522, so that the two extrusion frames 522 can be squeezed when they slide towards each other on the two side walls of the sliding track 3. When the driving cylinder 511 no longer drives the linkage frame 521 and the extrusion frame 522, the extrusion spring 8 can help the extrusion frame 522 to reset.

[0025] The test mechanism 2 includes a test body 201 and a connector 202. The test body 201 is arranged at the end of the operating table 1. The sliding track 3 is horizontally arranged in front of the test body 201. The connector 202 is an electrical connection structure. A plurality of connectors 202 are distributed on the test body 201 as a group, and the connector 202 is located above the sliding track 3. Figure 2 As shown, there are multiple connectors 202 distributed above both sides of the sliding track 3, so as to adapt to the connection between multiple points and electrical components. When the electrical component slides on the sliding track 3 and completes the insulation placement and relative positioning clamping, the two ends of the electrical component can be connected through the connector 202, and the electrical test can be carried out through the test body 201.

[0026] The scanning mechanism 4 includes a lifting cylinder 401 and a scanning head 402. The lifting cylinder 401 is arranged between the two test bodies 201, and the lifting end of the lifting cylinder 401 is opposite to the sliding track 3. The scanning head 402 is arranged on the lifting end of the lifting cylinder 401, and the scanning head 402 is located directly above the lifting block frame 611, so that the electrical components lifted by the lifting block frame 611 can be scanned in shape by the scanning head 402 to complete the shape detection of the electrical components. At the same time, the distance between the scanning head 402 and the electrical components can be controlled by the lifting cylinder 401, so that the scanning distance of the scanning head 402 can be adjusted according to the shape length of the electrical components.

[0027] Working principle: slide the electrical component forward through the sliding track 3. When the electrical component passes through the two positioning extrusion blocks 523, it will be guided to slide between the two positioning extrusion blocks 523. The electrical component will be located on the lifting block frame 611. At this time, the driving cylinder 511 is started to drive the driving shaft 512 to move upward. At this time, the telescopic push rod 621 at the end of the driving shaft 512 rises synchronously and squeezes the bottom end of the movable plug-in frame 612. The telescopic push rod 621 pushes the movable plug-in frame 612 to move upward, and the lifting block frame 611 above the movable plug-in frame 612 will lift the electrical component up. When the movable plug-in frame 612 rises to the highest point, the movable plug-in frame 612 will squeeze the bottom wall of the sliding track 3. At this time, the driving shaft 512 continues to rise, and the telescopic push rod 621 will shorten and squeeze the return spring 622 to compress. At the same time, during the rising process of the driving shaft 512, it can squeeze the sliding block part of the linkage frame 521 to slide up in the guide groove of the guide track 701, and as the sliding block moves upward, the connecting rod above the sliding block The frame will push the extrusion frame 522 to move horizontally on the side wall of the sliding track 3, and the two pushing extrusion frames 522 will slide in mirror symmetry. At this time, the positioning extrusion blocks 523 at the ends of the pushing extrusion frames 522 will move synchronously to each other, forming an opposite clamping and positioning of the electrical components that are lifted up. Since the lifting block frame 611 and the positioning extrusion blocks 523 are both made of insulating ceramic materials, the electrical components lifted by the lifting block frame 611 are clamped and positioned oppositely by the two positioning extrusion blocks 523, and the electrical components will be in an insulating state. After completion, the appearance of the electrical components can be detected by the scanning head 402 above the sliding track 3. At the same time, the two ends of the electrical components can be connected through the connector 202, and the electrical test can be carried out through the test body 201. After completion, the driving cylinder 511 is started to drive the driving shaft 512 to move downward, and the lifting insulation and opposite clamping positioning of the electrical components can be released synchronously and quickly, which is convenient for the next test of the electrical components, increases efficiency, and is more suitable for the test of a large number of electrical components.
