Description

Technical Field

[0001] This utility model relates to a relay calibration platform, and more particularly to a highly flexible relay calibration platform. Background Technology

[0002] Pumped storage power station power systems contain a large number of relays, necessitating regular calibration of relays of various specifications during power system operation. This prevents relays from malfunctioning or failing to operate due to increased contact resistance, ensuring stable power system operation. Based on this, existing relay calibration devices, as shown in patents 201710627590.4, 202122263943.1, and 202220471738.6, mainly consist of a power output terminal, a control terminal, a display screen, and multiple electrical rails. When calibrating a relay of any specification, the operator inserts the corresponding relay base into the electrical rail, then electrically connects the relay base to the power output terminal. The relay to be tested is then removed from the device and plugged into the relay base. The control terminal then powers on the relay, enabling the corresponding testing function.

[0003] However, the aforementioned device has a drawback: to facilitate the installation, removal, and replacement of the relay base for rapid testing of relays of different specifications, the relay base is simply fitted onto the outside of the electrical guide rail and left to slide freely. This makes the relay base susceptible to displacement due to external impacts during testing, potentially pulling on the connecting wires and affecting testing stability. Furthermore, to improve testing efficiency, operators may manipulate other relay bases during the testing of any given relay, increasing the likelihood of collisions with the relay base.

[0004] Therefore, a relay calibration platform is needed that can position the relay base in the testing state. Utility Model Content

[0005] The purpose of this invention is to provide a highly flexible relay calibration platform. It enables the positioning of the relay base and facilitates quick replacement of the relay base by operators after testing.

[0006] The technical solution of this utility model is as follows: A highly flexible relay calibration platform, including a calibration base, on which a power terminal, a control terminal, a display screen, and several electrical rails are respectively provided. Several relay bases are slidably connected to the electrical rails, and there is an electrical connection between the relay bases and the power terminal. A slide rail is provided on one side of the electrical rail, and a slider is slidably connected inside the slide rail. One end of the slider is provided with a column extending vertically above the slide rail. A fixing component is detachably connected to the top of the column. An insert plate is connected to the slider on one side of the column. A positioning strip is detachably connected to one end of the slide rail. Several slots extending to the outside of the slide rail are distributed at intervals on one side of the positioning strip. The insert plate is used to longitudinally limit the slider after it is inserted into the slot, and the fixing component is used to longitudinally limit the relay base.

[0007] In the aforementioned highly flexible relay calibration platform, a press-type self-locking buckle is connected to the slider, and the insert plate is glued to the side wall of the press-type self-locking buckle.

[0008] In the aforementioned highly flexible relay calibration platform, the press-type self-locking buckle includes a male buckle and a female buckle that engage with each other. The female buckle is fixedly connected to the slider, the lower end of the male buckle engages with the female buckle, and the other end of the male buckle extends to the outside of the slide rail and connects to the insert plate.

[0009] In the aforementioned highly flexible relay testing platform, the fixing element is an L-shaped elastic pressure plate, and the top and side of the column are connected to the elastic pressure plate by screws.

[0010] In the aforementioned highly flexible relay calibration platform, the slide rail has a C-shaped cross-section, and both ends of the slide rail are provided with bent portions for limiting the height of the slider. The positioning bar screw is connected to the bent portion on the side away from the electrical guide rail.

[0011] In the aforementioned highly flexible relay calibration platform, the slider is in the shape of a rectangular tube, and the female buckle is fastened to the middle of the slider and glued to it.

[0012] Compared with the prior art, this utility model has the following characteristics:

[0013] (1) This utility model enables the slider to move horizontally on the slide rail based on the position of the relay base through the structural cooperation of the slide rail and the slider. Through the structural cooperation of the insert plate and the positioning strip, the slider can be limited by inserting the insert plate after the slider moves into place. On this basis, the fixing parts set on the slider can be used to position the relay base after the slider is fixed, thereby effectively preventing the relay base from shifting during the detection process and ensuring its detection stability.

[0014] (2) By connecting the insert plate to the slider via a press-type self-locking buckle, the positioning stability of the slider can be guaranteed on the one hand, and the operation of the insert plate can be convenient for the operator to install and remove the insert plate on the other hand. That is, when the operator removes the insert plate, he only needs to pull the male buckle off the slider to release the limit of the slider, thereby realizing the rapid sliding of the slider.

[0015] (3) By using an elastic pressure plate as a fixing part and fastening and limiting the relay base, it is possible to ensure the positioning effect of the relay base while facilitating the operation of the operator; that is, when positioning, the operator only needs to move the relay base into place and then fasten the elastic pressure plate into the groove of the relay base. When releasing the positioning, the operator only needs to lift the elastic pressure plate and move the relay base away, thereby effectively improving the operation efficiency.

[0016] Therefore, this utility model can realize the positioning of the relay base and facilitate the quick replacement of the relay base by the operator after the inspection is completed. Attached Figure Description

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0022] Example. A highly flexible relay testing platform, configured as follows: Figure 1As shown, the device includes a calibration base 1, on which a power terminal 2, a control terminal 3, a display screen 4, and several electrical rails 5 are respectively provided. Several relay bases 6 are slidably connected to the electrical rails 5, and the relay bases 6 are electrically connected to the power terminal 2. A slide rail 7 is provided on one side of the electrical rails 5, and a slider 8 is slidably connected inside the slide rail 7. One end of the slider 8 is provided with a column 9 extending vertically above the slide rail 7. A fixing member 10 is detachably connected to the top of the column 9. An insert plate 11 is connected to the slider 8 on one side of the column 9. A positioning strip 12 is detachably connected to one end of the slide rail 7. Several slots 13 extending to the outside of the slide rail 7 are distributed at intervals on one side of the positioning strip 12. The insert plate 11 is used to longitudinally limit the slider 8 after it is inserted into the slot 13, and the fixing member 10 is used to longitudinally limit the relay base 6.

[0023] The slider 8 is connected to a press-type self-locking buckle, and the insert plate 11 is glued to the side wall of the press-type self-locking buckle.

[0024] The press-type self-locking buckle includes a male buckle 14 and a female buckle 15 that interlock with each other. The female buckle 15 is fixedly connected to the slider 8. The lower end of the male buckle 14 is connected to the female buckle 15. The other end of the male buckle 14 extends to the outside of the slide rail 7 and is connected to the insert plate 11.

[0025] The fastener 10 is an L-shaped elastic pressure plate, and the outside of the elastic pressure plate is wrapped with insulating tape. The top and side of the column 9 are connected to the elastic pressure plate by screws.

[0026] The slide rail 7 has a C-shaped cross-section. Both ends of the slide rail 7 are provided with bent portions for limiting the height of the slider 8. The positioning strip 12 is screwed onto the bent portion on the side away from the electrical guide rail 5.

[0027] The slider 8 is rectangular in shape. The female buckle 15 is fastened to the middle of the slider 8 and glued to the slider 8. The slider 8 has an opening for the male buckle 14 to be inserted.

[0028] The working principle of this utility model is as follows: When using this utility model, the operator first inserts the corresponding relay base 6 into the electrical guide rail 5 according to the specifications of the relay to be tested, and then connects the relay base 6 to the power terminal 2 through the power cord so that it can be tested through the calibration platform after the relay is plugged in.

[0029] After the relay base 6 is wired, the operator slides the slider 8 to one side of the relay base 6 according to its position. Then, the fixing piece 10 is placed in the groove of the relay base 6, so that the fixing piece 10 is snapped into the groove and tightly against the relay base 6 under the action of elasticity, thus achieving the positioning function. After the fixing piece 10 is placed, the operator inserts the male buckle 14 into the female buckle 15, and inserts the insert plate 11 on one side of the male buckle 14 into the corresponding slot 13. This uses the positioning strip 12 to limit the slider 8 and prevent the relay base 6 and the slider 8 from moving laterally when subjected to external impact.

[0030] When the relay base 6 needs to be replaced, the operator can lift the fixing part 10 to release the restriction on the relay base 6; when the longitudinal position of the slider 8 needs to be adjusted, the operator only needs to pull the male buckle 14 out of the female buckle 15 to release the restriction on the slider 8, and after the slider 8 moves into place, the male buckle 14 is reinserted for positioning, thus facilitating the operator's operation.
