Problems solved by technology

Since the condenser is directly connected to the evaporation space where the electrified heating element of the motor stator is located, if the pressure in the enclosed space for evaporative cooling is too high and the flow rate of the secondary cooling water is too small, the pressure of the entire system will be too high, which will directly affect the heat exchange of the condenser efficiency, but at the same time pose a safety hazard

Abstract

The monitor and protection control device for evaporation cooling system of motor stator comprises: an evaporation cooling chamber to make stator heat body and cooling medium contact directly, a condenser, a flux and pressure detection unit for re-cooling water, a gas exhaust unit, and an alarm system. Wherein, when the secondary water flow less than the set value or cutting water, the CPU unit [20] sends signal to alarm [25] to control adjustable valve [22] to regulate flow; when the pressure value more than set value 1, the CPU unit [20] sends signal to alarm [25]; when the pressure value more than set value 2, the CPU unit [20] sends signal to control switch [23] to control gas release valve [6] and exhaust gas to release chamber [7]. This invention improves running stability greatly.

Description

technical field [0001] The invention relates to a monitor, protection and control device for the evaporative cooling system of the horizontal and vertical generator stators. Background technique [0002] The evaporative cooling technology of the motor stator in the prior art is to soak the heat-generating parts of the motor stator in the liquid cooling medium, or pour the liquid cooling medium into the hollow conductor cavity of the motor stator winding, and use the principle of vaporization and heat absorption of the liquid cooling medium to cool the motor stator. [0003] In the monitoring and protection control device of the motor stator evaporative cooling system, the condenser is the main heat that takes away the heat generated by the motor stator heating parts, including the generator stator winding, iron core, and its fixed parts, so as to keep the motor temperature within the design limit. switch. Since the condenser is directly connected to the evaporation space w...
