Description

Technical Field

[0001] This utility model relates to the field of high-voltage wireless phase comparator technology, and in particular to a contact protection device for a high-voltage wireless phase comparator. Background Technology

[0002] A high-voltage wireless phase comparator is a specialized instrument used to detect the phase relationship between different power sources or lines in a high-voltage power system. It achieves non-contact phase comparison through wireless transmission technology, ensuring phase consistency during power system grid connection, loop closing, or equipment connection, thus guaranteeing the safe operation of the power grid. The phase comparator contacts may deform or break during high-voltage field operations due to accidental contact, drops, or collisions. The phase comparator contacts have a relatively thin structure and are susceptible to deformation or breakage during field operations or daily transport due to accidental contact, drops, or collisions, necessitating protection.

[0003] Existing high-voltage wireless phase comparator contact protection devices typically use a protective sleeve to cover the outside of the contacts, which is connected to the contact base via clips or threads. Before use, the protective sleeve must be rotated or pulled out to expose the contact surface. After the protective sleeve is removed, it must be placed manually, which can easily roll off or be lost due to a chaotic environment (such as scattered tools or uneven ground). Furthermore, the protective sleeve must be put back after the work is completed, making the process cumbersome, hindering the quick entry of the contacts into working condition, prolonging preparation time, and reducing testing efficiency.

Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A contact protection device for a high-voltage wireless phase comparator includes a movable rod, an insulating rod slidably connected to the outer side of the movable rod, a connecting block fixedly connected to one end of the insulating rod, a screw rod provided at one end of the movable rod, a receiver provided on the outer side of the screw rod, a contact body mounted at one end of the receiver, and an anti-slip sleeve provided on the outer side of the insulating rod. The device also includes:

[0007] A protective mechanism for quickly switching the protection state of the contact body is located on the outside of the moving rod. The protective mechanism includes an adjustment component, a positioning component, a protective cover, and a spring. The adjustment component is located on the outside of the moving rod, the positioning component is located on the inside of the connecting block, the protective cover is located on the outside of the contact body, and the spring is sleeved on the outside of the moving rod.

[0008] As a preferred embodiment of the high-voltage wireless phase comparator contact protection device of this utility model, the protection mechanism further includes a connecting component, a limiting component, a transmission component, and a guiding component.

[0027] Example 1:

[0028] Reference Figures 1-4 This is the first embodiment of the present invention, which provides a contact protection device for a high-voltage wireless phase comparator. The device includes a movable rod 1, with an insulating rod 2 slidably connected to the outer side of the movable rod 1. Both the movable rod 1 and the insulating rod 2 are made of epoxy resin, possessing excellent electrical insulation properties, effectively isolating high-voltage power lines and operators to prevent electric shock accidents. A connecting block 3 is fixedly connected to one end of the insulating rod 2, and a screw 7 is provided at one end of the movable rod 1. A receiver 4 is provided on the outer side of the screw 7 and threadedly connected to a mounting base at the bottom of the receiver 4. The receiver 4 can be installed or removed from one end of the movable rod 1 by rotating it. The receiver 4 is used to receive signals collected by the contact body 5. The contact body 5 is installed at one end of the receiver 4, which is the part of the high-voltage wireless phase comparator that directly contacts the high-voltage line under test, and is used to collect the phase signal of the high-voltage line. This is existing technology and will not be elaborated further here; the outer side of the insulating rod 2 is provided with an anti-slip sleeve 6, which is made of rubber and can enhance the friction when gripping the insulating rod 2; it also includes: a protection mechanism 8 for quickly switching the protection state of the contact body 5, which is set on the outer side of the moving rod 1. The protection mechanism 8 includes an adjustment component 81, a positioning component 84, a protective cover 86 and a spring 87. The adjustment component 81 is set on the outer side of the moving rod 1, the positioning component 84 is set on the inner side of the connecting block 3, and the protective cover 86 is set on the outer side of the contact body 5. The protective cover 86 is made of polycarbonate and has the characteristics of high strength, impact resistance and excellent insulation performance. It is used to cover the outer side of the contact body 5 for protection when it is idle, and its inner wall can slide along the outer side of the base of the contact body 5 when the protective cover 86 moves; the spring 87 is sleeved on the outer side of the moving rod 1. The spring 87 is made of insulating material and is used to reset the moving rod 1 after it moves.

[0029] Example 2:

[0030] Reference Figures 1-4 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0031] The protection mechanism 8 also includes a connecting component 82, a limiting component 83, a transmission component 85, and a guide component 88. The connecting component 82 is located outside the adjusting component 81, the limiting component 83 is located outside the connecting component 82, the transmission component 85 is located outside the moving rod 1, and the guide component 88 is located outside the transmission component 85.

[0032] The adjustment assembly 81 includes a pull ring 811 fixed to one end of the moving rod 1 for pulling the moving rod 1 to move and adjust the position of the protective cover 86; a connecting seat 812 is fixedly connected to the outside of the pull ring 811.

[0033] The connecting assembly 82 includes a connecting rod 821 that rotates inside the connecting seat 812. The other end of the connecting rod 821 is rotatably connected to a rotating seat 822. After the connecting rod 821 moves with the connecting seat 812 and rotates along its inner side, its other end will rotate with the rotating seat 822 and drive it to move.

[0034] The limiting component 83 includes a guide block 831 fixed to one side of the rotating seat 822. A limiting groove 832 is formed on the inner wall of the connecting block 3. The outer side of the guide block 831 is slidably connected to the inner side of the limiting groove 832. The connecting rod 821 is rotatably connected to the guide block 831 through the rotating seat 822. When the connecting rod 821 rotates, it will drive the guide block 831 to slide along the inner side of the limiting groove 832. The limiting groove 832 guides the movement path of the guide block 831 and ensures the stability of the rotation of the connecting rod 821.

[0035] The positioning component 84 includes a movable frame 841 that slides on the inner wall of the connecting rod 821. Two insert rods 842 are fixedly connected to the outer side of the movable frame 841. Two slots 843 are opened on the inner wall of the connecting block 3. The movable frame 841 can slide along the slots on the inner wall of the connecting rod 821. One end of the insert rod 842 is made of rubber. After the insert rod 842 is inserted into the inner side of the slot 843, the insert rod 842 will be squeezed by the inner wall of the slot 843. Since the diameter of the insert rod 842 is slightly larger than the hole diameter of the slot 843, and the rubber material itself has a certain elasticity, a large friction force will be generated, which effectively prevents the insert rod 842 from coming out of the slot 843 and fixes the connecting rod 821 and the connecting block 3, ensuring that the spring 87 cannot rebound.

[0036] The transmission assembly 85 includes a limiting block 851 fixed to the outside of the moving rod 1. A connecting frame 852 is fixedly connected to the outside of the limiting block 851. The outside of the connecting frame 852 is fixedly connected to one end of the protective cover 86. Since one end of the spring 87 is fixed to one end of the insulating rod 2, when the moving rod 1 moves backward, it will squeeze and limit the spring 87 with the limiting block 851. When the moving rod 1 is no longer fixed, the elastic force of the spring 87 is released, and the kinetic energy will be transmitted through the limiting block 851 to make the moving rod 1 complete the reset.

[0037] The guide assembly 88 includes a fixed rod 881 fixed to the outside of the limiting block 851. A guide seat 882 is fixedly connected to the outside of the insulating rod 2. The outside of the fixed rod 881 is slidably connected to the inner wall of the guide seat 882. When the limiting block 851 moves, it will slide the fixed rod 881 along the inner side of the guide seat 882. The guide seat 882 will restrict the movement path of the fixed rod 881 and make the limiting block 851 move in a parallel direction.

[0038] During use, when testing is required, the operator needs to hold the anti-slip sleeve 6 with one hand and pull the moving rod 1 backward through the pull ring 811 with the other hand. At this time, the limiting block 851 moves accordingly, compressing the spring 87, and the connecting bracket 852 moves the protective cover 86 backward, exposing the contact body 5 for testing. Simultaneously, due to the change in its position, the connecting seat 812 causes the connecting rod 821 to move accordingly and rotate as a whole along its inner side. The rotating seat 822 carries the guide block 831 to slide downward along the limiting groove 832. When the connecting rod 821 and the connecting... After block 3 forms a vertical angle, the moving frame 841 is pushed forward, causing the insertion rod 842 to engage inside the slot 843. Subsequently, the connecting rod 821 enters a fixed state, supporting the moving rod 1 and limiting the spring 87 to prevent it from rebounding. After the test is completed, the moving frame 841 is pushed backward, causing the insertion rod 842 to disengage from the inside of the slot 843, and the connecting rod 821 is rotated upward. Then, the spring 87 loses its limit, pushing the limiting block 851 to reset, and causing the moving rod 1 to move forward as a whole. At this time, the connecting frame 852, with the protective cover 86, is re-covered on the outside of the contact body 5 to protect it.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
