Abstract

The low-pressure water-turbine generator set black switch comprises a protection box, a supporting block is fixedly connected to the center of the bottom of an inner cavity of the protection box, and a speed regulator body is fixedly connected to the top of the supporting block. The first motor, the rotating rod, the first gear, the chain, the second gear and the rotating vane are additionally arranged on the basis of original mechanical parts, the heat dissipation and dehumidification effects can be achieved, the service life of the machine is prolonged, and through the motor, the energy accumulator, the gear pump, the corresponding control valve set, the rough oil filter, the electric contact pressure gauge and the like, the service life of the machine is prolonged. The energy accumulator achieves the functions of pressure maintaining, pressure stabilizing and an auxiliary power source, high-pressure nitrogen is filled in the energy accumulator, gas and oil are isolated, oil is not prone to oxidation, the energy accumulator can be used for three to six years after being filled with gas once, gas filling is convenient, the cleaning period is prolonged as much as possible, cleanliness of pressure oil is guaranteed, and when all power sources disappear, a water turbine can be effectively closed, and the energy accumulator is safe and reliable. When the governor body oil pipe breaks and applies pressure, the water turbine can be timely and effectively closed.

Description

technical field [0001] The invention relates to the technical field of hydro-generators, in particular to the black-off of a low-pressure hydro-generator set. Background technique [0002] The microcomputer governor of hydraulic turbine is a new type of hydraulic turbine governor developed on the basis of electro-hydraulic governor in the 1970s. With the development of computer technology and control theory, the technology of hydraulic turbine governor is also constantly developing and improvement, the reliability and adjustment quality have fully met the requirements of unmanned duty and few people in power plants. The existing hydraulic turbine microcomputer governor has poor automation effect, resulting in the failure of the machine to be shut down in time, which not only reduces the hydraulic turbine microcomputer The use efficiency of the governor also brings trouble to the staff. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide th...
