Rated voltage |
Usually applicable to 40.5kV and below indoor high - voltage electrical equipment, such as 6kV, 12kV, 20kV, 27.5kV, 35kV, etc. |

Display function |
Can display the charged status of high - voltage circuits. |
Can display the charged status of high - voltage circuits. |
Locking function |
May have a certain locking function, but the specific mode and strength need to be determined according to the manufacturer's design. |
Has a forced locking function. When the high - voltage circuit is charged, it can forcibly lock the operating handle and door of the switchgear through an electromagnetic lock to prevent misoperation. |
Self - checking function |
May or may not have a self - checking function, depending on the specific product model. |
Usually has a self - checking function to ensure the normal operation of the equipment. |
Phase - checking and voltage - testing function |
May not have this function. |
Usually has phase - checking and voltage - testing functions to meet the needs of more comprehensive power equipment detection. |
Circuit design |
The internal circuit is relatively complex due to the addition of relevant functional modules. |
The internal circuit is more complex, and additional space is required to arrange relevant circuit modules and components to adapt to functions such as phase - checking, voltage - testing, and locking. |
Applicable scenarios |
Applicable to some occasions where the requirements for anti - misoperation and safety are relatively high, but the specific requirements for functions are slightly different from those of DXN8DQ. |
More suitable for important power places where strict safety protection requirements are required and misoperation prevention is needed, such as large - scale substations and high - voltage switchgear in urban central substations. |
