Introduction
GB/T 30844 "1 kV and below general frequency conversion speed regulation equipment" aims to standardize the technical conditions of 1 kV and below general frequency conversion speed regulation equipment.
It is planned to consist of three parts. test materials, test methods, inspection rules and safety regulations.
--Part 1.Technical conditions. The purpose is to provide the rated values, operating conditions and
Technical requirements.
--Part 2.Test methods. The purpose is to provide test methods for general variable frequency speed regulating equipment of 1 kV and below.
-- Part 3.Safety regulations. The purpose is to provide the electrical, thermal and energy requirements for general variable frequency speed control equipment of 1 kV and below.
Safety requirements other than power supply.
General frequency conversion speed regulation equipment of 1 kV and below
Part 2.Test methods
1 Scope
This document describes the test methods for general purpose variable frequency speed regulating equipment (hereinafter referred to as "speed regulating equipment") of 1 kV and below.
This document is applicable to rated input voltage of 1 kV AC and 1.5 kV DC and below, rated input frequency of 50 Hz or 60 Hz,
Inspection and acceptance of speed regulating equipment with output voltage not exceeding 1 kV and output frequency less than 600 Hz.
Note. Speed regulating equipment with rated input voltage of 1 140 V or output frequency greater than 600 Hz is also usually implemented in accordance with this document.
To be determined through negotiation between the manufacturer and the user.
