Electrified oiling device for distribution transformer

Abstract

The invention relates to an oiling device, in particular to an electrified oiling device for a distribution transformer. The electrified oiling device can operate in an electrified mode and comprises a first support, a second support and a through hole cone, wherein the through hole cone can be placed on an oil injecting opening in the transformer, and a hollow oil pipe is arranged on the through hole cone. The lower end of the hollow oil pipe is connected with a floating ball, an oil bag is arranged on the first support and connected with a wireless electric oil valve, the wireless electric oil valve is connected with the hollow oil pipe through an insulated soft oil pipe, and a wireless remote control transmission camera capable of shooting the oil-injection condition of the transformer is arranged on the second support. Electrified oiling of the distribution transformer can be achieved, the operation and maintenance level of the transformer is greatly increased, electricity-selling benefits are increased, the oil deficiency condition of the transformer is treated in time, and safe and stable operation of a whole power distribution net is guaranteed.

Description

technical field [0001] The invention relates to a refueling device, in particular to a live refueling device for a distribution transformer capable of live operation. Background technique [0002] With the rapid development of the national economy, the requirements for the reliability of power supply are getting higher and higher. The reliability management of power distribution facilities has been raised to a certain level. The reliability management of power supply equipment is mainly to strictly assess unplanned outages, and focus on the management of the maintenance process and quality of maintenance. After the oil level of the distribution transformer drops, it will not only cause the sealing and insulation of the equipment to drop, but also affect the working status of the equipment, and even cause serious losses to the equipment. [0003] The reasons for the drop in the oil level of distribution transformers can be roughly divided into the following categories: (1) S...

Problems solved by technology

After the oil level of the distribution transformer drops, it will not only cause the sealing and insulation of the equipment to drop, but also affect the working status of the equipment, and even cause serious losses to the equipment.

[0003] The reasons for the drop in the oil level of distribution transformers can be roughly divided into the following categories: (1) Seasonal oil level changes. After adjusting the oil level in summer, it will decrease due to the drop in ambient temperature in autumn and winter; Or the quality of maintenance is poor, and there is oil leakage from the equipment body; (3) Due to changes in the operating conditions of the equipment, such as oil injection in the distribution transformer during a short circuit, etc.

[0004] The conventional refueling method of distribution transformer equipment is to open the switch on the high-voltage side and the low-voltage side, install a set of grounding wires on both sides, then open the oil filling hole with a wrench, put a funnel, and start pouring transformer oil with an oil barrel to fill up After that, restore the cover and let it stand for a period of time (remove the air bubbles in the oil and the impurities washed up at the bottom of the quick refueling will naturally sink to the bottom, these will affect the insulation performance of the transformer oil, and in severe cases, it will cause insulation breakdown and burn the transformer), resume power transmission

The current refueling method needs to invest a lot of manpower, material resources and unplanned equipment outage time to maintain it, which has caused direct economic losses and social benefits to the power company; moreover, the resulting frequent power outages and power transmission operation and maintenance, increasing the possibility of accidents
