Description

Electronic cradle extension device Technical Field The utility model relates to the technical field of electric measuring tools, in particular to an electronic megger extension device. Background The electronic cradle is an instrument for detecting insulation resistance of electric equipment, mainly composed of medium-large scale integrated circuits, and has the characteristics of large output power, high short-circuit current value and multiple output voltage classes. The working principle is that the built-in battery is used as a power supply, DC/DC conversion is carried out to generate direct-current high voltage, then I/V conversion is carried out to complete operation through the divider, and finally the measured insulation resistance value is displayed on the LCD screen. Electronic rockers are commonly used to check the insulation resistance of electrical equipment, household appliances or electrical lines to ground and to the phases, so as to ensure that these equipment work in normal conditions, avoiding accidents such as electric shock casualties and equipment damage. In practical use, because of the design limitation of the cradle, the measuring range is often limited, especially when electronic components at a far distance or a narrow space need to be measured, operators need to enter the space, so that the operation is inconvenient, and the risk of electric shock exists.
