Embodiment 1

[0026] Such as Figure 1-6 As shown, the present invention provides a technical solution: a substation high-voltage arrester leakage current abnormal alarm device, including a leakage current meter 1 and a mounting plate 12, the front of the leakage current meter 1 is fixedly installed with a dial 2, and the inside of the dial 2 is fixedly installed with a sliding The rheostat 3 is provided with a scale inside the dial 2, and the scale and the sliding rheostat 3 are arranged in an arc shape, the sliding rheostat 3 is installed on the lower part of the scale, and the inside of the dial 2 is equipped with a pointer 4, The pointer 4 is a sliding vane type, and the bottom end of the leakage ammeter 1 is fixedly installed with the first connecting column 5, and the end of the leakage ammeter 1 far away from the first connecting column 5 is fixedly installed with the second connecting column 6, and the bottom of the leakage ammeter 1 is fixedly installed Device box 7 is arranged, an...

Embodiment 2

[0029] Such as Figure 1-6 As shown, on the basis of the first embodiment, the present invention provides a technical solution: an installation hole 13 is opened inside the installation plate 12 , and an installation groove 14 is opened at the bottom of the installation plate 12 .

[0030] In this embodiment, by setting the installation hole 13, by inserting the bolt inside the installation hole 13, the installable plate 12 can be fixed in the installation column of the lightning arrester, and by setting the installation groove 14, the bottom of the device box 7 is located in the installation groove 14 , the installation of the device box 7 and the leakage ammeter 1 is conducive to the installation of the device box 7 and the leakage ammeter 1.

Embodiment 3

[0032] Such as Figure 1-6 As shown, on the basis of Embodiment 1 and Embodiment 2, the present invention provides a technical solution: a central cylinder 18 is fixedly installed on the back of the leakage ammeter 1, a cavity 26 is opened inside the locking disc 21, and the central cylinder 18 and The specifications and dimensions of the cavity 26 are suitable.

[0033] In this embodiment, when the leakage ammeter 1 is installed, the central barrel 18 is put into the cavity 26 , which is beneficial to the connection between the leakage ammeter 1 and the locking plate 21 , thereby facilitating the installation of the leakage ammeter 1 .

Abstract

The invention discloses a transformer substation high-tension lightning arrester leakage current abnormity alarm device, which comprises a leakage ampere meter and a mounting plate, a sliding variableresistance sheet is fixedly mounted in a dial plate, a pointer is fixedly mounted in the dial plate, and a sensitive sensor is fixedly mounted in a device box. And a microprocessor is fixedly installed in the device box, a displayer is fixedly installed in the device box, a display lamp is fixedly installed on the front face of the device box, limiting hooks are fixedly installed on the two sidesof the outer portion of a fixing cylinder, and clamping blocks are fixedly installed at the top and the bottom of the inner wall of an annular connecting groove. By refitting the structure of an existing lightning arrester leakage ampere meter, the problem that the abnormal state of the leakage ampere meter is not easy to find in the inspection process is solved, the abnormal condition of the leakage current is obviously displayed, operation and maintenance personnel can conveniently master the state of substation equipment, and the inspection efficiency and quality of the substation are improved.

Description

technical field [0001] The invention belongs to the technical field of alarm devices, and in particular relates to an alarm device for abnormal leakage current of a high-voltage arrester in a substation. Background technique [0002] One of the daily important tasks of the substation is equipment inspection. It is necessary to transcribe the leakage current of the lightning arrester in the station to judge whether the leakage current value is normal, and whether the deviation of the leakage current value of the lightning arrester between the three phases is within a certain range. If there is any abnormality, according to the severity of the abnormality, It is necessary to stop the operation in time to avoid the explosion accident of the arrester. With the increasing number of unattended substations, the ratio of substation operation and maintenance personnel to stations continues to decrease, and fewer people need to manage more equipment. However, there are a large number ...
