Description

Technical Field

[0001] The utility model relates to the technical field of indicators, in particular to an indicator for calibrating a transformer tripping outlet. Background Art

[0002] A line fault indicator is an electric power monitoring device installed on a line. When an abnormality occurs in a transformer line, the line fault indicator will send out a specific signal or light mark to remind the staff to perform maintenance in a timely manner. The emergence of the line fault indicator not only greatly increases the operating safety of the staff, but also greatly reduces the labor intensity of the staff. However, the existing transformer tripping outlet calibration indicator still has certain shortcomings. For example, when the indicator is connected and installed with the line, it is very cumbersome and cannot achieve the effect of quick connection. Sometimes even a single person cannot complete the installation. For this reason, we propose a transformer tripping outlet calibration indicator. Utility Model Content

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Embodiment 1:

[0018] See also Figure 1-2The utility model provides a technical solution: an indicator for transformer tripping outlet calibration refers to an electric power equipment, which can be installed on the line to monitor the state of the transmission line and detect faults in the line, including an indicator body 1, and an outer protective shell 2 is provided on the outer periphery of the indicator body 1. The outer protective shell 2 can protect the indicator body 1 from being exposed to the sun and rain, thereby extending its service life. Telescopic sleeves 3 are provided at the centers of the front and rear end surfaces of the top of the indicator body 1, and hooks 4 are provided at the top of the telescopic sleeves 3. A clamping component 5 is provided at the center of the top of the indicator body 1. When connecting the indicator body 1 to the line, the entire indicator body 1 can be hung on the line through the hook 4. At this time, the telescopic sleeve 3 is in a stretched state, and then the staff can push the indicator body 1 upward to shrink the telescopic sleeve 3, so that the position of the indicator body 1 can be adjusted, and then the clamping component 5 is used to clamp the fixed line to complete the connection and installation. The clamping assembly 5 includes a base 6, a curved groove 7 is longitudinally arranged at the top center of the base 6, a curved clamping plate 8 is arranged on the top of the base 6, and hinges 9 are hingedly arranged between the front and rear end surfaces of the left bottom of the curved clamping plate 8 and the front and rear end surfaces of the left top of the base 6. When the indicator body 1 is adjusted to a suitable height, the circuit will be placed in the curved groove 7, and then the curved clamping plate 8 is covered to the top of the base 6 by the hinge 9. A fixing block 10 is arranged at the bottom center of the right side of the curved clamping plate 8, and a bolt 11 is arranged between the top of the fixing block 10 and the right side of the top of the base 6. After the arc clamping plate 8 is covered, the fixing block 10 is connected to the base 6 by the bolt 11, so that the overall indicator body 1 and the circuit can be quickly and effectively connected and installed. The inner wall of the curved groove 7 and the inner wall of the inner cavity of the curved clamping plate 8 are both provided with an anti-slip layer 12. The anti-slip layer 12 can increase the stability and avoid the indicator body 1 from moving on the line during use.

[0019] Among them, preferably, the anti-skid layer 12 is configured as a flexible rubber anti-skid layer, and the surface of the flexible rubber anti-skid layer is evenly provided with anti-skid convex grooves. This configuration can increase the anti-skid performance and avoid the phenomenon that the clamping component 5 cannot effectively clamp the circuit after installation, thereby causing the indicator to move.

[0020] Preferably, the outer wall of the hook 4 is sleeved with a rubber protective sleeve, which can not only prevent slipping but also have certain insulation protection performance. The angle between the hook 4 and the indicator body 1 is set to ninety degrees. This setting can avoid the phenomenon of the overall indicator being offset after installation.

[0021] Preferably, long foot bolts are vertically penetrated all around the top of the base 6, and threaded holes matching the long foot bolts are provided all around the top of the indicator body 1. This arrangement can not only increase the stability of the connection between the base 6 and the indicator body 1, but also enable the base 6 of different sizes, that is, the overall clamping assembly 5, to be disassembled and replaced according to the thickness of the line.

[0022] Embodiment 2:

[0023] Reference Figure 1-2 , this embodiment is different from the first embodiment in that: the outer protective shell 2 is set to an "n" shape, and a circular groove is set on the top of the outer protective shell 2. The circular groove can facilitate the connection between the clamping assembly 5 and the indicator body 1. Fixing bolts are set around the top of the outer protective shell 2 and the top of the indicator body 1. This arrangement can increase the stability of the connection between the outer protective shell 2 and the indicator body 1; arc baffles are set on the tops of the front and rear end surfaces of the arc-shaped clamping plate 8. The arc baffles can play a rain-proof effect and prevent rainwater from directly splashing on the position where the arc-shaped clamping plate 8 and the base 6 clamp the circuit. The arc baffle and the arc-shaped clamping plate 8 are an integrally formed structure. The integrally formed arc baffle and the arc-shaped clamping plate 8 have strong structural stability and are not easy to break.

[0024] The electrical appliances mentioned in this article are all connected to an external power source through wires.

[0025] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
