Abstract

The invention relates to the technical field of corrosion protection, and specifically discloses a device used for drum type filter screen potential measurement. The device comprises a potential detector, a reference electrode device, an electric brush probe and a telescopic pole, wherein the reference electrode device is connected to the front end of the telescopic pole through a reference electrode guide wire; the reference electrode device is fixed to the tail end of the telescopic pole; the electric brush probe is connected to the potential measurer through the electric brush probe guide wire, so that the reference electrode device, the electric brush probe and the potential detector define a loop. The device used for drum type filter screen potential measurement can realize fixed-period convenient measurement of drum type filter screen protective potential, can protect the potential detector and staff operation by utilizing a magnetic connecting way of the reference electrode device and the telescopic pole, utilizes a gasbag in the reference electrode device, and can conveniently recycle the reference electrode device which drops accidentally.

Description

technical field [0001] The invention belongs to the technical field of corrosion protection, and in particular relates to a device for measuring the potential of a drum-shaped filter screen. Background technique [0002] The function of the drum-type rotary filter screen in nuclear power plants is to remove fine debris in seawater to ensure the normal operation of subsequent equipment. Whether the drum screen can operate normally has a great impact on the power plant. The drum grid of the power plant has been in highly corrosive seawater for a long time, so sacrificial anodes are installed on the drum grid to protect the drum grid and slow down corrosion. The cathodic protection standard requires that after the sacrificial anode is installed on the equipment, it should be regularly measured whether its protection potential meets the requirements. The measurement amount of the protection potential shall be measured at least once every 0.5a in the initial period (after instal...
