[0032] The transformer monitoring and alarm system of this embodiment includes a monitoring part, a calculation part, and a result display part;

[0033] The monitoring part includes a temperature monitoring unit for monitoring overheating faults, a vibration monitoring unit for monitoring mechanical faults of the on-load tap changer and iron core windings, a ground current monitoring unit for monitoring multi-point grounding faults of the iron core, and a monitoring unit for partial discharge Faulty partial discharge monitoring unit, gas chromatography monitoring unit for calculating the content of various typical gases in oil, and water content monitoring unit for calculating the water content in transformer oil;

[0034] The calculation part is a computer for receiving monitoring data of each unit;

[0035] The schematic diagram of the data connection between the monitoring part and the calculation part is as follows: figure 1 shown.

[0036] It should be noted that the s...

specific Embodiment 2

[0043] The transformer monitoring and alarm system of this embodiment is further defined on the basis of the specific embodiment 1: seven beam-splitting prisms 6 are arranged on the seven-color parallel light beam, and an image sensor 7 is arranged on the reflected light path of each beam-splitting prism 6, so The image sensor 7 is connected to the calculation part.

[0044] The results of the transformer monitoring and alarm system in this embodiment show a partial structural diagram as shown in Figure 4 shown.

[0045] The transformer monitoring and alarm system of the present embodiment can analyze whether each parallel light beam has an output result according to the ratio of each layer in the image sensor 7, and it is considered that there is an output result when the calculation result of the layer ratio exceeds a threshold. The calculation result is set to 1, otherwise it is set to 0. This embodiment provides a specific implementation manner for encoding seven-color p...

specific Embodiment 3

[0047] The transformer monitoring and alarm system of this embodiment is further defined on the basis of specific embodiment 1 or specific embodiment 2: it also includes a corner cube prism 8, and the corner cube prism 8 and the parallel beam light source 3 are arranged on a beam splitting glass plate 4 on the same side, after the parallel beam emitted by the parallel beam light source 3 irradiates the beam-splitting glass plate 4, the reflected beam irradiates to the center of the corner cube prism 8, and the corner cube prism 8 makes the beam return to the original path without loss.

[0048] Based on the specific embodiment 1, the result display part of the structural diagram of the transformer monitoring and alarm system in this embodiment is as follows: Figure 5 shown.

[0049] The setting of the corner cube prism 8 in this embodiment utilizes the principle of total reflection, so that the light beam reflected from the beam splitting glass plate 4 is irradiated to the be...

Description

technical field [0001] The invention belongs to the field of power systems, and in particular relates to a transformer monitoring and alarm system. Background technique [0002] With the advancement of west-to-east power transmission, north-south mutual supply, and national networking, the scale of my country's power grid and the scale of power transmission are constantly expanding, and grid security issues have become increasingly prominent. The statistical results of power grid accidents during my country's "Eleventh Five-Year Plan" show that power equipment failures account for the first cause of power grid accidents. It can be seen that the safe operation of power equipment is the primary task of avoiding power grid accidents, and the safe operation of power transformers is the top priority of this task. [0003] In order to ensure the safe operation of the transformer, it is necessary to monitor the operation status of the transformer. At present, there have been vari...
