Technical Field
[0001] The utility model relates to the technical field of phase verification devices, in particular to a phase verification device for a high-voltage switch cabinet. Background Art
[0002] Phase verification refers to using a phase detector or other means to check whether the phases and phase sequences of two power sources or loops are the same during electrical operations in a power system. That is to say, in actual power operation, the measurement of the phase difference. If the phase sequences are inconsistent, it will lead to interphase short-circuit accidents and affect normal power transmission;
[0003] When the existing phase verification device is in use, the staff needs to hold the X-rod and the Y-rod, and use the tip contacts of the X-rod and the Y-rod to touch the conductor on the same phase. The receiver can reflect whether it is the same phase. When the tip contacts are touching, since the existing tip contacts do not have a buffer structure, and at the same time, since the tip contacts are relatively thin, when the staff applies a large force, the tip contacts are prone to bending;
[0004] In addition, dust is likely to accumulate on the surface of the conductor inside the high-voltage switch cabinet. When there is a lot of dust on the surface of the conductor, it will cause poor contact between the tip contact and the conductor. Therefore, a phase verification device for a high-voltage switch cabinet is proposed to solve the above problems. Summary of the Utility Model
[0005] The purpose of the utility model is to solve the problem that the existing tip contacts in the prior art do not have a buffer structure, and at the same time, since the tip contacts are relatively thin, when the staff applies a large force, the tip contacts are prone to bending, and a phase verification device for a high-voltage switch cabinet is proposed.
[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0007] A phase verification device for a high-voltage switch cabinet includes a receiver and a detection rod body that establishes an information transmission connection with it. There are two detection rod bodies. An outer protective cylinder is rotatably connected to the surface of the detection rod body near the tip contact. A runner is rotatably connected to the surface of the detection rod body near the insulating rod. An insulating connecting rod is fixedly connected between the runner and the outer protective cylinder. An inner protective cylinder is slidably arranged inside the outer protective cylinder. The inner protective cylinder is sleeved on the surface of the tip contact.
[0008] Preferably, a limiting chute is opened on the inner wall of the outer protective cylinder, and a slider that is slidably connected to the limiting chute is fixedly connected to the surface of the inner protective cylinder.
[0009] Preferably, a plurality of fan-shaped plates distributed in a circumferential manner are rotatably connected to the inner wall of the inner protective cylinder, and a closing spring is fixedly connected between the side wall of the fan-shaped plate and the inner wall of the inner protective cylinder.
[0010] Preferably, gaskets are symmetrically arranged between the inner protection cylinder and the end of the detection rod body, and buffer springs are fixedly connected between the gaskets.
[0011] Preferably, a cleaning disc is fixedly connected to one end of the inner protective cylinder, and a brush for cleaning dust is provided on the surface of the cleaning disc.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] 1. The utility model is provided with an outer protective cylinder, an inner protective cylinder and a buffer spring. Before the tip contact contacts the conductor, the cleaning disk contacts the conductor first, so that the inner protective cylinder squeezes the buffer spring, which can buffer the initial force when hitting the conductor, and then the tip contact slowly extends out of the inner protective cylinder to contact the conductor, thereby avoiding the phenomenon of bending of the tip contact due to excessive resistance force.
[0014] 2. The utility model is provided with a cleaning disk, an insulating connecting rod and a rotating wheel. The staff can use the thumb to turn the rotating wheel, and then drive the outer protective cylinder to rotate through the insulating connecting rod, and then drive the inner protective cylinder to rotate. The inner protective cylinder drives the cleaning disk to rotate, and the bristles can be used to clean the dust on the surface of the conductor to ensure the stability of the contact between the tip contact and the conductor.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0021] Referring to Figures 1-4 , a phase verification device for a high-voltage switch cabinet, including a receiver 2 and a detection rod body 1 that establishes an information transmission connection with it. There are two detection rod bodies 1. An outer protection cylinder 5 is rotatably connected to the surface of the detection rod body 1 near the tip contact. A runner 3 is rotatably connected to the surface of the detection rod body 1 near the insulating rod. An insulating connecting rod 4 is fixedly connected between the runner 3 and the outer protection cylinder 5. An inner protection cylinder 7 is slidably arranged inside the outer protection cylinder 5. The inner protection cylinder 7 is sleeved on the surface of the tip contact. Gaskets 10 are symmetrically arranged between the end of the inner protection cylinder 7 and the detection rod body 1. A buffer spring 9 is fixedly connected between the gaskets 10.
[0022] It should be noted that: before the tip contact touches the conductor, the cleaning disc touches the conductor first, and then pushes the inner protection cylinder 7. The inner protection cylinder 7 will compress the buffer spring 9, so as to buffer the initial force during contact, so that the tip contact extends out of the inner protection cylinder 7 to contact the conductor, avoiding the phenomenon that the tip contact is bent due to excessive contact force.
[0023] A limiting chute is opened on the inner wall of the outer protection cylinder 5. A slider 8 that is slidably connected to the limiting chute is fixedly connected to the surface of the inner protection cylinder 7.
[0024] It should be noted that: ensure that the inner protection cylinder 7 can only slide up and down inside the outer protection cylinder 5 and cannot rotate, and ensure that the outer protection cylinder 5 can drive the inner protection cylinder 7 to rotate, and then drive the cleaning disc to rotate.
[0025] A plurality of sector plates 12 distributed in a circular pattern are rotatably connected to the inner wall of the inner protection cylinder 7. A closing spring 11 is fixedly connected between the side wall of the sector plate 12 and the inner wall of the inner protection cylinder 7.
[0026] It should be noted that: under the action of the closing spring 11, the sector plates 12 can be automatically closed to realize the protection function of the tip contact.
[0027] A cleaning disc 6 is fixedly connected to one end of the inner protection cylinder 7. Brush hairs 13 for cleaning dust are arranged on the surface of the cleaning disc 6.
[0028] It should be noted that: by turning the rotating wheel 3 with the thumb, the rotating wheel 3 drives the outer protective cylinder 5 to rotate through the insulating connecting rod 4, the outer protective cylinder 5 drives the inner protective cylinder 7 to rotate, and the inner protective cylinder 7 drives the cleaning disk to rotate, so as to realize the function of cleaning the dust on the surface of the conductor.
[0029] When the present utility model is in use, when a staff member holds the detection rod body 1 and contacts the conductors of the same item, the cleaning disk 6 contacts the conductor first. At this time, by turning the rotating wheel 3 with the thumb, and then driving the cleaning disk to rotate through the insulating rod, the dust on the surface of the conductor can be cleaned;
[0030] When the cleaning disk abuts against the conductor, it will push and press the inner protective cylinder 7 and then compress the buffer spring 9, so as to buffer the initial force during abutment, make the tip contact buffer and extend out of the inner protective cylinder 7, and slowly contact the conductor, avoiding the bending phenomenon of the tip contact due to excessive initial abutment force, and realizing the protection function of the tip contact.
[0031] The above is only the preferred specific implementation mode of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent replacement or change, and should be covered within the protection scope of the present utility model.
