Embodiment Construction

[0018] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] Please combine Figure 1 to Figure 2 As shown, a kind of main transformer oil chromatography on-line monitoring system provided by the present invention comprises: several main transformers 1, the main transformer oil tank 5 on each main transformer 1 is all connected with an oil chromatography on-line monitor 2, above-mentioned is The prior art part will not be repeated here. Different from the prior art, the top of each main transformer oil tank 5 is provided with an oil filling port 51 and an air pressure measuring hole 52. The oil filling port 51 is used to inject transformer oil, and a barometer 6 can be installed on the air pressure measuring hole 52. The measuring range of the barometer 6 is 30kPa~110kPa, and the measurement uncertainty is less than or equal to 0.2kPa. The bottom of the main transformer oil tank...

Abstract

The invention discloses an on-line monitoring system of main transformer oil chromatography. The system comprises a plurality of main transformers; an oil tank arranged on each main transformer is connected with an oil chromatography online monitoring device; an oil filling port and an air pressure measuring hole are formed in the top of each main transformer oil tank; and an oil discharge port isformed in the bottom of the main transformer oil tank. Besides, an interface connected with the oil chromatography on-line monitoring device is also arranged on each main transformer oil tank and isconnected with the oil chromatography online monitoring device via a flange; and each oil chromatography online monitoring device is connected with a sub control computer by a network and is used forcollecting information of the connected oil chromatography online monitoring device. In addition, the system also includes a main control unit; each sub control computer is connected with the main control unit via the network. The main control unit comprises a main control computer and a centralized control platform server. Therefore, the worker can master the operation conditions of all transformers in time in a master control room.

Description

technical field [0001] The invention relates to an oil chromatographic on-line monitoring system, in particular to a main transformer oil chromatographic on-line monitoring system. Background technique [0002] Transformer is one of the important equipment in the power system, and its operation reliability directly affects the safe operation of the power system. The composition and content of dissolved gases in transformer oil are closely related to the degree of transformer insulation aging or failure. Therefore, the analysis of dissolved gases in oil is one of the most effective measures to check the operation status of transformers, especially for oil-filled electrical equipment. It is of great significance to make correct judgment and analysis of equipment failure due to the existence of latent failures. [0003] Since it is impossible to install only one transformer in the entire power system, multiple transformers are required to operate simultaneously in the power sy...
