COOLER OUT EQUIPMENT FOR A COOLER OF GENERATOR}

The present invention relates to a generator cooler take-out apparatus, and more particularly, to take out a cooler in combination with a slide member and a cooler when taking out a cooler in a space in which a cooler is stored to maintain and repair a bulky and heavy generator cooler. After seating on the upper end of the horizontal support member provided with the member can be taken out of the cooler more easily by using the withdrawal member, there is a support means that can be moved to move the generator cooler take-out device for the withdrawal operation, The present invention relates to a cooler takeout device for a generator that is easy to draw out a cooler.

In general, power plants have facilities for converting thermal energy and mechanical energy into electrical energy, and rotate the turbine using energy sources such as water, oil, coal, natural gas, and nuclear power, and produce electricity through a generator connected to the turbine. For example, hydroelectric power plants, thermal power plants, and nuclear power plants are classified according to the type of energy source used and the power generation method.

The generator, a device that converts thermal energy and mechanical energy into electrical energy, generates high heat from the generator itself due to the high-speed rotational force delivered from the turbine and the high-pressure power produced by the generator. As the temperature rises above the critical temperature, and safety accidents such as a breakdown or explosion of the power generation facility installed at a high cost may occur, the generator is prevented from overheating by using a cooler and maintained below an appropriate threshold point. You should be able to.

The cooler needs periodic maintenance and maintenance. To maintain and maintain the cooler, the cooler, which is stored in a certain space of the power plant, must be taken out of the storage space.

However, a large volume and heavy weight cooler is difficult to use heavy equipment due to the narrow working space when it is drawn out for maintenance. Withdrawal.
