AC test load box AC380V0-300KW dummy load three-phase resistive test load cabinet AC380V-300KW Product Category: AC R load box Product Number: AC380V-300KW Product Description: Spot products can lease for on-site testing generators, UPS and other testing services Product details I. 1 Product Overview AC380V-300KW three-phase AC load box built purely resistive load; can simulate a variety of power load to meet generators, UPS, inverter and other AC full load testing needs, the production workshop, laboratory, installation, research and development necessary testing tools. Host has a temperature overheat alarm protection: overheating due to special reasons, it can automatically cut off the load. Whole by the resistive load components. Load using energy method, using forced air cooling mode. Axial fan with a small fan, with air flow, heat dissipation, low noise characteristics. The above features make the machine in safety, reliability, noise reduction is superior to imported products. 2, the relevant standards and specifications (1) "Power, reactors and similar products - Part 1: General requirements" GB 19212.1-2008 (2) "Safety of machinery - electrical equipment Part 1: General technical conditions" GB 5226.1-2002 ( 3) "Low-voltage switchgear and control equipment General" GB / T 14048.1-2000 (4) "Marine diesel generator set" GB / T 13032-2010 (5) "military engine load general specification" GJB 2815-97 (6) " AC load-moving military general specification "GJB 235A-97 (7)" workers, IF moving load General technical conditions "GJB 235-87 (8)" Common test methods for military engine load "GJB 1488-93 (9)" Design of Industrial Enterprises health standards "GBZ1-2002 Second, the technical parameters of the load box test dummy load three-phase AC resistive test load AC380V0-300KW cabinet 1.

Altitude: ≤2500 meters three resistive load module resistive load module consists of a number of special nickel-chrome alloy resistive connection is made. Alloy resistive element as a power by special alloy processing, external material made of 304 stainless steel heat sink, filling the middle by an insulating medium, in which the resistance of the package to meet the needs of the load test. Alloy resistance insulation properties, high thermal performance, even heat conduction, the operating temperature of only 1/3 of the design temperature, low temperature drift, resistance stable, long working hours without red hot. And with acid, salt spray, rain, moisture, corrosion effects, all-weather use. Resistive load module uses proprietary technology, the alloy resistive insulating material fixed plate, the entire module sealing process, through internal insulation and insulation plate two isolated, even in wet weather but also to ensure insulation and security, and the prevention phase o resistance due to the internal resistance due to reduced short circuit accident.
