Description

TECHNICAL FIELD

[0001] The utility model relates to a quick contact type distance fine adjustment device, especially a quick contact type distance fine adjustment device for switch station. BACKGROUND

[0002] A pumped storage power station is a hydroelectric station that uses electricity to pump water to an upper reservoir during low demand periods and then releases the water to generate electricity during peak demand periods. It is also known as a storage hydroelectric station. It can convert excess electricity during low demand periods into high value electricity during peak demand periods, and is also suitable for frequency and phase modulation to stabilize the frequency and voltage of the power system. The dam of the pumped storage power station plays a crucial role in the operation of the power station. It can store water, and the dam is used to form a reservoir in the upper reservoir to store water pumped from the lower reservoir during low demand periods. The stored water is released during peak demand periods to meet the demand for electricity through hydroelectric power generation. It can also store and regulate seasonal rainfall to reduce the threat of floods to downstream areas. During heavy rain or floods, the dam can store excess water to reduce the pressure of floods downstream.

[0003] The existing power station unit is usually provided with a servomotor feedback device, and whether the feedback signal is accurate will directly affect the regulation accuracy of the speed regulator. When the servomotor feedback device is reinstalled and the feedback steel wire rope zero point is adjusted, it is difficult to adjust the zero point, and the steel wire rope is often displaced when the fastening bolt is tightened, resulting in failure of the check.
