Description

Technical Field

[0001] The invention relates to the technical field of electrical measurement, in particular to a novel electronic megohmmeter. Background Art

[0002] The new electronic megohmmeter is a test instrument with innovative design and advanced functions. It integrates intelligent technology and remote control capabilities, providing a more efficient, accurate and convenient solution for electrical insulation testing, and has the following functions: It has an automatic range switching function, which can automatically select the appropriate measurement range according to the resistance value of the object being measured to ensure the accuracy of the measurement results; it can automatically record and store measurement data for subsequent analysis and processing; it adopts advanced measurement technology and can provide high-precision insulation resistance measurement results to meet various strict test requirements; it is equipped with a clear and easy-to-understand display screen, which displays measurement data and test status in real time, making it convenient for operators to quickly obtain information; it adopts high-quality materials and advanced manufacturing processes, has good anti-interference ability and durability, and can operate stably in harsh working environments; The new electronic megohmmeter has a wide range of applications. It is used for insulation resistance testing of substation equipment, transmission lines, etc. to ensure the safe operation of the power system. It is suitable for regular maintenance and troubleshooting of electrical equipment such as motors, transformers, switch cabinets in factories, and for detecting the insulation condition of lines and equipment during the electrical installation and acceptance of buildings.

[0003] The existing new electronic megohmmeters all need to be placed horizontally on a plane for use and measurement, but most of the megohmmeters do not have an automatic adjustment mechanism to make them horizontal, which leads to reduced measurement efficiency or further affects the stability of the measurement.

The measurement result of the insulating megohmmeter has high requirements for the horizontal state. If the megohmmeter is not in a horizontal state, the precision measuring elements inside it will be affected by the uneven gravity.
