Description

Technical Field

[0001] The utility model relates to the technical field of constant potential instruments, in particular to a combined cathode protection constant potential instrument. Background Art

[0002] As the name suggests, a constant potential instrument is a device that can continuously provide protective current to keep the potential of the protected metal object constant. Its principle is to rectify and regulate the 220V AC power in the room, and then convert it into DC power as cathodic protection current to be transmitted to the protected metal object.

[0003] The constant potential instrument automatically adjusts the output current by real-time monitoring of the cathodic protection power-on potential, forcing the potential of the protected metal object to be stabilized within a reasonable value, thereby achieving the cathodic protection effect. The impressed current cathodic protection range provided by a constant potential instrument can usually cover tens of kilometers of pipelines. At the same time, due to the large output current, it can be used to protect uncoated exposed metals such as grounding grids.

[0004] In the prior art, when a ship uses a constant potential meter to protect the hull, the constant potential meter needs to be fixed in the engine room of the hull by bolts. The humidity in the engine room is relatively high, which is not conducive to the normal operation of the constant potential meter. When installing it in the engine room, the space in the cabin is small, and it is very inconvenient to install it directly by bolting. The installation is relatively complicated, which is not conducive to the installation and replacement of the constant potential meter. Utility Model Content

A threaded cover is detachably installed on the outer side of the threaded opening through a thread and a sealing gasket. A mesh bag is fixedly installed on the right side of the threaded cover, and a dehumidifying agent is contained in the mesh bag.

[0011] Furthermore, an air inlet is provided on the right side wall of the seat body, and the outer side of the air inlet is connected to the blower through an air inlet pipe.

[0012] Furthermore, heat dissipation grilles are arranged around the outer side of the cabinet, and the heat dissipation grilles are used to dissipate heat and ventilate.
