Provided are a voltage measurement method and apparatus. The method includes following steps: a number j of height values are selected in a vertical direction of a transmission line, a number m of sensors used for measuring, according to a Stark effect, electric field strength of a corresponding spatial position are arranged in sequence at each of j spatial positions of the j heights from the ground, electric field strength values of the corresponding spatial position are measured through the m sensors respectively, and an electric field strength average value of the corresponding spatial position is calculated according to the acquired m electric field strength values, where j and m are positive integers, and the j spatial positions are below the transmission line; a voltage of the transmission line is calculated according to j electric field strength average values.

Voltage measurement method and apparatus

A combined-type intelligent terminal wiring device and a plug device are provided. The wiring device includes a top wiring terminal board, a bottom wiring terminal board and a combined-type socket. An interior of each terminal of the combined-type socket has a spring-leaf structure, and each spring leaf includes an upper spring leaf and a lower spring leaf which are conductively connected via a contact surface. The top wiring terminal board has one end configured to connect the upper spring leaf, and the bottom wiring terminal board has one end configured to connect the lower spring leaf. The plug device includes a plug and a wiring terminal, the plug is located at a front end of the plug device and is a conductive metallic sheet, and the wiring terminal is located at a rear end of the plug device and has one end connected to the conductive metallic sheet.
