Product Overview
The MOEORW-372N electroscope test stand is developed in strict accordance with the requirements of Preventive Test Regulations for Electric Safety Tools (Trial) (Guo Dian Fa [2002] No.777) and fully complies with national standards and DL740-2014 industry specification. This testing device is specially designed for functional performance inspection of 10kV–500kV high-voltage electroscopes used in all power industry sectors. It can complete three core standard tests for electroscopes: startup voltage detection, same-direction interference electric field test, reverse interference electric field test. The whole set is split into two size specifications to match different voltage grades, with adjustable sliding guide rails to precisely control electrode spacing, supporting two types of electroscopes (with/without extended contact electrodes) for standardized, repeatable laboratory preventive testing of safety tools.
Application
1.Power supply bureaus, power transmission & distribution companies
2.Power construction engineering enterprises, power maintenance teams
3.Electric power safety tool inspection laboratories & third-party testing institutions
4.Thermal power, hydropower, new energy power station safety departments
5.Metallurgy, chemical, mining enterprises with internal high-voltage power distribution rooms
6.Vocational electric power colleges, electrical safety training bases Core usage: Regular preventive performance test of high voltage electroscopes before on-site power operation, to verify whether electroscopes can normally alarm under specified voltage and resist external electric field interference.
1.Standard-compliant Design Fully follows DL740-2014 & national power safety tool test regulations; two interchangeable grading ring sizes cover full 10kV–500kV voltage range.
2.Adjustable Sliding Guide Rail Structure Equipped with scale-marked mobile trolley, accurately adjust electrode spacing to standard values for two types of electroscopes, ensures test consistency.
3.Integrated Mobile Base with Casters Separate small trolley for electroscope clamping + main guide rail trolley, universal casters for easy movement and fixed positioning during testing.
4.Complete Test Function Coverage Supports all three mandatory electroscope performance tests: startup voltage, same-direction interference, reverse interference electric field test.
5.Safe High-Voltage Test Layout Independent grounding terminal design, one-point grounding system, clear high-voltage separation layout to avoid electric shock risk during testing.
6.Easy Maintenance & Long Service Life Detachable insulating support tubes, lubricatable linear guide rails, smooth sliding, stable insulating performance, easy daily cleaning and maintenance.
7.Dual Test Modes Compatible Suitable for electroscopes with and without extended contact electrodes, one set of equipment meets all mainstream electroscope test demands of power industry.
