Title

AC Wound Rotor Motor

Brief Introduction

YR series ac wound rotor motor is a new generation product based on the company's long-term stable high-voltage three-phase asynchronous motor's experience of design and manufacturing, combined with the latest international standards.

Some or all of the following equipment will be required for satisfactory operation of generators covered by Clause 6, depending on the design of the coolant and auxiliary systems. The list is not intended to be complete in all details, and other items may be provided.

a) A complete coolant gas system (hydrogen or other gas), with suitable regulators to control the gas pressure in the generator, suitable for connecting to the gas supply, a gas dryer and a means of checking or monitoring the daily gas consumption.

b) A complete system for the purging gas (usually carbon dioxide) suitable for connecting to the gas supply, to permit the casing to be safely filled with and scavenged of hydrogen. If the pressurized air system of the power station is used to drive the scavenging gas from the casing, the connection to the air system shall be arranged to ensure that air cannot be released into the generator except to remove the scavenging gas, for example by having a removable pipe connection.

c) Necessary indicators and alarm devices to enable the required degree of purity of hydrogen to be maintained and to enable the purity of the scavenging gas to be monitored while the casing is being emptied of hydrogen. Two independent means for indicating purity should be provided.

d) A complete seal oil system including equipment for monitoring the seal oil and, if required, for removing gas and water from it. An emergency supply of seal oil shall be provided, to operate automatically if the main supply fails.

e) A complete liquid cooling system (or systems) with pumps, coolers and filters, and with suitable regulators to control the temperature of the cooling liquid.

f) Means of detecting the reduction or loss of flow of liquid through the windings.

g) Means of measuring the conductivity of water used for cooling the windings and maintaining it at a sufficiently low value.

h) Measuring instruments and alarms to indicate the functioning of all auxiliary apparatus and the presence of liquid in the generator; also means for removing the liquid
