A substation applied protection cabinet's plate function and dysfunction contrast apparatus is provided, relating to a contrast plate for a substation applied protection cabinet's plate. The contrast apparatus is provided to solve the problem rising from the operation to have a protection cabinet's plate function and stop function in prior art. In prior art, there is no contrast, and a workman can only do the operation based on memories. This makes it easy to cause accidents when the function and dysfunction go wrong. Further, in prior art, the reminding plate is also difficult to operate, wastes paper and is not provided with protective measures. The contrast apparatus provided by the utility model makes a number of protection plates evenly distributed and locked tight in a transparent box, and each of the protection plate is provided with a high light reflection glass ball; the high light reflection glass balls are provided with lights; when the electricity conducting sheets are closed, the lights are communicated with the power supply. The fact that the lights illuminate suggests that the plates are closed so that a workman could do contrast more directly. The utility model is suitable for doing contrasts for the operation of plates on their function and non-function.
