标准简介：This part of IEC 60947 specifies rules for control units, which perform the switching functions
in response to the thermal detectors incorporated in rotating electrical machines according to
IEC 60034-11, and the industrial application.
It specifies rules for that type of system comprising a positive temperature coefficient (PTC)
thermistor detector having particular characteristics, and its associated control unit.
The PT100 detectors are covered by IEC 60751, where the resistor values are given
according to the temperatures of the detector.
The present rules lay down the characteristics of association of this particular positive
temperature coefficient thermistor detector and its associated control unit (designated “Mark A
detector” and “Mark A control unit”), when they are used in thermal protection systems.
NOTE It is not possible to specify all the requirements for the operating characteristics of a control unit, as they
are dependent on some aspects of the thermal detectors. Some aspects of the requirements of the thermal
protector system can only be specified when account is taken of the characteristics of the rotating machine to be
protected and the method of installation of the detector within the machine.
For these reasons, for each characteristic it is necessary to specify who is responsible for stating the required
values and who is responsible for compliance with the requirement and for carrying out any confirmatory test.
