GB/T 43028-2023 Particular requirements for load-shedding equipment(LSE)
Basic Information
Scope
This document specifies the technical requirements for load shedding equipment, including marking and documentation, protection against electric shock, structure, mechanical performance, and electrical performance. The purpose of this document is to provide requirements for energy efficiency system equipment. This document covers load shedding equipment (LSE). The safety standards for LSE follow the provisions of IEC Guide 110. This document applies to load shedding equipment (LSE) for household and similar applications. The load shedding function is used in energy management systems to optimize the overall use of electrical energy, including production and storage. Load shedding can be used for energy efficiency purposes as specified in IEC 6036481:2019. This document applies to the normal operation of LSE under the following conditions: -- rated frequency of 50 Hz, 60 Hz, or both, with a rated voltage not exceeding 440 V (phase-to-phase) and a rated current not exceeding 125 A, and a rated short-circuit capacity not exceeding 25,000 A in an AC circuit; or -- DC circuit 1). LSE is intended to control the energy supplied to one or more loads, circuits, or power grids when: -- specified time and current conditions are reached; -- a command or information is received from an external system. LSE is intended for use in: -- a single device with all necessary means of controlling loads (for example, energy management functions are integrated into such devices); or -- a unit integrated into a more complex device, or as a standalone device part of an energy efficiency management system (EEMS); or -- an LSE assembled from independent devices (for example, an LSE with an external current sensor); or -- a combination of the above. LSE may have a wireless interface. LSE is part of a fixed installation. 1) LSE for DC circuits are currently under consideration.
