Scope

This chapter of GB/T 14536.1-2022 is applicable except for the following contents. Replacement: This document is applicable to the partial evaluation of thermal protectors for household and similar motors defined in GB/T 14536.1, including those used in heating, air conditioning and similar purposes, as well as hermetic (hermetic and semi-hermetic) motor-compressors Motor thermal protector in. Note: The motor thermal protector is considered as an integral controller, its protective function depends on the correct installation and fixing inside or on the surface of the motor, and it can only be combined with the relevant motor for complete testing. This dependence is illustrated by the following points: ---The motor thermal protector can accurately and reliably sense the heating of the motor windings, which solves the problem of excessive temperature of the motor when it is overloaded; ---The motor thermal protector can accurately and reliably Induction of the current value when the motor is locked, thereby reducing the response time of the thermal protector and protecting the assembly point from adverse effects of heat dissipation problems; — the electromagnetic field of the motor affects the breaking action of the motor thermal protector, especially the contactor The direction of the arc between the points causes uneven wear of the contact material, which eventually leads to operational failure. The combined test requirements for hermetic (hermetic and semi-hermetic) motor-compressors and motor thermal protectors are in IEC60335 2
