The purpose of the utility model is to realize through following technical scheme; A kind of electrified tester for zinc oxide arrester; Its main points are that it mainly comprises current sampling box, wireless voltage sampling box, wireless data acquisition terminal box; Current sampling box outside is complete airtight metal shell; Internal circuit comprises that Zinc-Oxide Arrester, electric current pointer gauge, counter, rectification sampling amplification circuit, AD circuit, machinery change electric signal processing circuit, high-speed microprocessor, scrambler, wireless synchronization transmitter module, wireless synchronization and accepts module; Ground connection behind Zinc-Oxide Arrester and rectification sampling amplification circuit, electric current pointer gauge, counter, the polyphone; Counter changes electric signal processing circuit through machinery and links to each other with high-speed microprocessor; The rectification sampling amplification circuit links to each other with high-speed microprocessor through the AD circuit, and high-speed microprocessor is accepted module and linked to each other with scrambler, wireless synchronization transmitter module, wireless synchronization respectively, and wireless voltage sampling box is made up of A, B, C three whiles sample circuit; A, B, three sample circuits of C link to each other with voltage box high-speed microprocessor respectively; Voltage box high-performance single-chip microcomputer is accepted module and is linked to each other with voltage box scrambler, voltage box wireless synchronization transmitter module, voltage box wireless synchronization respectively, and the wireless data acquisition terminal box comprises that high-performance single-chip microcomputer, wireless synchronization transmitter module, wireless synchronization accept module, and the high-performance single-chip microcomputer has the RS232 interface.
The data of gathering are achieved remote monitoring through wireless transmission, realize the electricity isolation between monitor and the control center.Even a monitor is struck by lightning like this, can not impact other monitors and control center yet.Mechanical counting unit of discharge and reometer leakage current measurement unit are added that the data cell collection that teletransmission collects is an one, are enclosed within fully in the metal shell that favorable sealing property is not affected by the external environment.
Respectively be added with a fuse at wireless voltage sampling box A, B, three sample circuit leading portions of C, occurring can not producing any influence under the situation of short circuit the system of transformer station.
The utility model increases the wireless synchronization transmitter module through giving in each parts, wireless synchronization is accepted module; Make between each parts data and instruction transmission can realize remote transmission; This lightning arrester is long-range/on-the-spot dual-purpose on-line monitoring device reasonable in design; Data are observed convenient, can effectively carry out continuous monitoring.Encode for each wireless electric current sampling box or voltage sampling box.So just can on host computer, discern that lightning arrester very easily, just can have the big lightning arrester of electrorheological repeatedly to monitor targetedly.
