Intelligent inner-oil type metal bellows expansion oil conservator

Abstract

An intelligent inner-oil type metal bellows expansion oil conservator is applied to an electric power system, is configured with oil-immersed transformers and electric power equipment, and mainly comprises an inner-oil type oil conservator, a level sensor and a signal processor. The intelligent inner-oil type metal bellows expansion oil conservator is characterized in that the level sensor is mounted on the inner-oil type oil conservator and is connected with the signal processor through a shielded wire so as to form a smart oil level signal output system of the intelligent inner-oil type metal bellows expansion oil conservator. The operation principle includes that when oil temperature of the transformer is increased or reduced to cause changes of the oil level of the oil conservator, oil level change signals are transmitted to the signal processor by the level sensor, and then collected and processed to be transmitted to a computer, so that the oil level is displayed in real time; meanwhile, the oil level value of the oil conservator is sent to mobile phones of management staff through a communication network, so that the management staff can check the oil level through short messages of the mobile phones to realize oil level remote monitoring.

Description

Technical field: [0001] The invention relates to an intelligent internal oil type metal corrugated expansion oil conservator applied in the electric power system, specifically, it is an intelligent monitoring system when the oil level of the oil conservator changes due to the change of the oil temperature of the transformer, or when the transformer is faulty An intelligent system for real-time oil level monitoring and alarming. Background technique: [0002] Under the new situation of the development of the national electric power industry, the planning and operation of the smart grid put forward higher requirements for the supporting components of the electric power equipment. As an important component in the operation of the transformer, the oil conservator protects the oil quality of the transformer and compensates the change in the oil volume of the transformer. Therefore, the research on the intelligent oil conservator is embodied in the intelligent monitoring of the oi...

AI Technical Summary

Problems solved by technology

[0004] 1. The oil level signal of the traditional oil conservator cannot be transmitted far away and the oil level can be monitored throughout the process, and accurate data cannot be provided for statistical analysis of oil level changes;

[0005] 2. The traditional oil storage tank does not have the function of visually displaying the online oil level of the oil storage tank, and the real-time oil level cannot be monitored by the computer in the monitoring room;

[0006] 3. The traditional oil conservator does not have the function of transmitting the oil level signal to the mobile phone of the monitoring personnel in time, and it is not possible to use the mobile phone text message to check the oil level in time and deal with the accident in time

Not suitable for unattended power stations and smart grid requirements,
