Description

Technical Field

[0001] The present invention relates to the technical field of relay protection tests, and particularly to a relay protection test device for an intelligent substation. Background Art

[0002] Relay protection tests are a very important link in the power system, aiming to verify whether the functions of relay protection devices are normal, and ensure that when a fault occurs in the power system, the relay protection devices can quickly and accurately cut off the fault, guaranteeing the safe and stable operation of the power system.

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

[0004] Currently, for the tests of each energized connection component of the relay protection device, in addition to the electrical performance tests, an appearance inspection is also required to ensure the integrity of the components. When facing a large number of electrical component tests and detections, it is generally completed on the operating table. During this process, due to the need to conduct a large number of electrical tests, and during the test process, the electrical components need to be insulated and placed, and at the same time, the positions of the electrical components need to be locked to facilitate subsequent power-on tests. Most of the insulation placement and locking structures of the existing relay protection test devices are separate. During actual operation, insulation placement and locking need to be completed separately. When transferring the components for other tests, the insulation placement and locking need to be unlocked again, reducing the test efficiency.

Detailed implementation manners

[0029] 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.

[0030] Reference Figures 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;

[0031] 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;

[0032] Component lifting mechanism 6, the component lifting mechanism 6 includes a jacking chassis 61 and a synchronous jacking assembly 62. A groove is provided on the bottom wall of the sliding track 3. The jacking chassis 61 includes a jacking block frame 611 and a movable insertion frame 612. The movable insertion frame 612 is vertically arranged through the bottom wall of the sliding track 3. The jacking block frame 611 is arranged to fit the groove on the bottom wall of the sliding track 3, and the top surface of the jacking block frame 611 is flush with the bottom wall of the sliding track 3. The jacking block frame 611 is an insulating ceramic block frame. The movable insertion frame 612 passes through the frame of the bottom wall of the sliding track 3 and is connected to the jacking block frame 611. The synchronous jacking assembly 62 is arranged between the driving assembly 51 and the sliding track 3, and the synchronous jacking assembly 62 acts on the movable insertion frame 612, so that when the driving assembly 51 drives the two linkage frames 521 to move upward, it can synchronously drive the movable insertion frame 612 to move upward, enabling the two extrusion frames 522 to move synchronously upward on the side walls of the sliding track 3 while moving oppositely, helping to lift the electrical components to be tested in the sliding track 3. Through the insulating ceramic jacking block frame 611, the insulating effect on the electrical components to be tested can be achieved, thereby quickly completing the processes of jacking insulation and opposite extrusion positioning of the electrical components, and enabling the electrical components to quickly enter the state to be measured.

[0033] 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 platform 1. The driving shaft 512 is arranged on the output end of the driving cylinder 511, and the driving shaft 512 is directly opposite to the bottom surface of the operating platform 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 platform 1, and the guiding mechanism 7 acts on the linkage frame 521.

[0034] The guiding mechanism 7 includes guiding tracks 701 and limiting grooves 702. Two guiding tracks 701 are arranged in a mirror-symmetrical manner in a group on the bottom wall of the operating platform 1, and guiding grooves are provided on the opposite side walls of the two guiding tracks 701. The limiting grooves 702 are provided on the inner walls of the guiding grooves. The linkage frame 521 includes a connecting frame and a sliding block. The sliding block is arranged to fit the guiding groove of the guiding track 701. Connecting frames are provided at both the upper and lower ends of the sliding block. 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. One end of the connecting frame located above the sliding block is rotatably connected to the extrusion frame 522, and the other end is rotatably connected to the sliding block. As Figure 8 shown, when the driving shaft 512 rises, it can squeeze the sliding block to slide upward in the guiding groove of the guiding track 701, and at the same time, push the extrusion frame 522 to move horizontally on the side wall of the sliding track 3 through the connecting frame;

[0035] Among them, convex blocks are provided on both sides of the sliding block, and the convex blocks are arranged to fit the limiting grooves 702. Through the restriction of the limiting grooves 702 on the convex blocks, the sliding of the sliding block in the guiding track 701 can be guided and restricted.

[0036] The synchronous jacking 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 drive shaft 512, and the top of the telescopic push rod 621 faces the movable insertion frame 612 directly. The telescopic push rod 621 includes two rod bodies. One rod body is fixedly arranged at the end of the drive shaft 512, and the other 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. When the two rod bodies of the telescopic push rod 621 shorten, the return spring 622 will be compressed, and the telescopic push rod 621 can maintain a restoring tendency. When the driving cylinder 511 drives the drive shaft 512 to rise, the telescopic push rod 621 rises synchronously and presses against the bottom end of the movable insertion frame 612. The telescopic push rod 621 pushes the movable insertion frame 612 to move upward. When the movable insertion frame 612 rises and presses against the bottom wall of the sliding track 3, the drive shaft 512 continues to rise, and the telescopic push rod 621 will shorten. At this time, the return spring 622 is compressed by extrusion. When the driving cylinder 511 drives the drive 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 return to its original length;

[0037] Through one driving cylinder 511 and the drive shaft 512, the telescopic push rod 621 is driven to rise to squeeze the jacking block frame 611 and the movable insertion 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 towards each other on the two side walls of the sliding track 3, and the positioning squeezing blocks 523 are used to clamp the jacked electrical components towards each other, so as to quickly complete the effect of jacking first and then positioning towards each other, and improve the efficiency.

[0038] As Figure 3 and Figure 4 shown, the positioning squeezing block 523 is a trapezoidal block made of insulating ceramic material, and the positioning squeezing blocks 523 at the ends of the two squeezing frames 522 are mirror-symmetrical. The groove on the bottom wall of the sliding track 3 and the component lifting mechanism 6 are both located between the positioning squeezing blocks 523. As Figure 3As shown, the jacking block frames 611 are evenly distributed in the groove on the bottom wall of the sliding track 3, and the length of the jacking block frame 611 is greater than the length of the positioning extrusion block 523, so that the jacking range of the jacking block frame 611 is larger than the clamping range of the positioning extrusion block 523, enabling it to adapt to the jacking and clamping of various large-length electrical components. The narrow sides of the positioning extrusion blocks 523 face each other, and tooth blocks are provided on the narrow sides of the positioning extrusion blocks 523, which can increase the clamping force when clamping the electrical components. There is a gap between the positioning extrusion block 523 and the bottom wall of the sliding track 3, and the height of the gap is the same as the rising height of the jacking block frame 611. After the jacking block frame 611 of the component lifting mechanism 6 jacks up the large-length electrical component, the positioning extrusion block 523 can clamp the two sides of the electrical component in opposite directions, keeping the large-length electrical component in the middle position above the jacking block frame 611, and at the same time, it can also form clamping and positioning of the large-length electrical component, preventing the large-length electrical component from tilting on the jacking block frame 611 and causing the two ends to contact the bottom wall of the sliding track 3, damaging the insulation.

[0039] As Figure 3 and Figure 4 shown, the two positioning extrusion blocks 523 form a channel with wide sides and a narrow middle in the inner side of the sliding track 3, so that when the large-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 wider can guide the electrical component to move to the middle part between the two positioning extrusion blocks 523. At this time, the middle part of the large-length electrical component will be located on the jacking block frame 611, facilitating subsequent jacking and clamping positioning in opposite directions.

[0040] An extrusion spring 8 is provided 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. When the two extrusion frames 522 slide towards each other on the two side walls of the sliding track 3, the extrusion spring 8 can be squeezed. 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 reset.

[0041] The test mechanism 2 includes a test main body 201 and a connector 202. The test main body 201 is arranged at the end of the operating table 1, the sliding track 3 is horizontally placed in front of the test main body 201, the connector 202 is an electrical connection structure, multiple connectors 202 are distributed in a group on the test main body 201, and the connector 202 is located above the sliding track 3. As Figure 2 shown, multiple connectors 202 are distributed above the two sides of the sliding track 3, so as to be able to adapt to the connection with the electrical component at multiple points. When the electrical component slides into the sliding track 3 and completes insulation placement and clamping positioning in opposite directions, the two ends of the electrical component can be connected through the connector 202, and electrical tests can be carried out through the test main body 201.

[0042] The scanning mechanism 4 includes a lifting cylinder 401 and a scanning head 402. The lifting cylinder 401 is arranged between two test bodies 201, and the lifting end of the lifting cylinder 401 faces the sliding track 3 directly. 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 subjected to external shape scanning through the scanning head 402 to complete the external 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, which is convenient for adjusting the scanning distance of the scanning head 402 according to the external shape length of the electrical components, etc.

[0043] Working principle: Slide the electrical component forward through the sliding track 3. When the electrical component passes through the two positioning and squeezing blocks 523, it will be guided to slide between the two positioning and squeezing blocks 523. The electrical component will be located on the lifting block frame 611. At this time, start the driving cylinder 511 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 will rise synchronously and squeeze against the bottom end of the movable plug frame 612. The telescopic push rod 621 will push the movable plug frame 612 to move upward. The lifting block frame 611 above the movable plug frame 612 will lift the electrical component upward. When the movable plug frame 612 rises to the highest point, the movable plug 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 upward movement of the driving shaft 512, it can squeeze the sliding block part of the linkage frame 521 to slide upward in the guiding groove of the guiding track 701. As the sliding block moves upward, the connecting frame above the sliding block will push the pushing and squeezing frame 522 to move horizontally on the side wall of the sliding track 3. The two pushing and squeezing frames 522 slide symmetrically. At this time, the positioning and squeezing blocks 523 at the ends of the pushing and squeezing frames 522 will move toward each other synchronously to form an opposite clamping and positioning of the lifted electrical component. Since both the lifting block frame 611 and the positioning and squeezing blocks 523 are made of insulating ceramic material, when the electrical component lifted by the lifting block frame 611 is oppositely clamped and positioned by the two positioning and squeezing blocks 523, the electrical component will be in an insulating state. After completion, the external shape detection of the electrical component can be carried out through the scanning head 402 above the sliding track 3. At the same time, the two ends of the electrical component can be connected through the connecting head 202, and electrical tests can be carried out through the test body 201. After completion, start the driving cylinder 511 to drive the driving shaft 512 to move downward, and quickly release the lifting insulation and opposite clamping and positioning of the electrical component synchronously, which is convenient for carrying out the next test of the electrical component, improving the efficiency and being more suitable for testing a large number of electrical components.
