Description
Technical Field
The utility model relates to an electrode especially relates to platinum electrode.
Background
In some cooling systems of high-voltage power equipment, in order to clamp the potential difference of the cooling liquid, water electrodes need to be arranged at different positions of a cooling pipeline to ensure that the potential differences of the cooling liquid at different positions are equal. Platinum metal is an excellent water electrode material because it has very excellent electrochemical inertness. Generally, to reduce the cost, platinum plating of stainless steel is used as the electrode portion material. However, for some demanding applications, pure platinum is still required as an electrode material for water electrodes.
At present, a thin-walled tube is processed at one end of a stainless steel electrode body, and a platinum needle is plugged into the thin-walled tube and then is shrunk through rolling processing to compress the platinum needle. The structure is very easy to cause the problem that the platinum needle is loosened in the using process. The main reasons for this include two, the first: the stainless steel thin-walled tube can partially rebound after being rolled, so that the stainless steel thin-walled tube is not really pressed; secondly, the method comprises the following steps: the platinum material is soft and easy to deform, and can generate plastic deformation under the dynamic impact of flowing cooling liquid in long-term use, so that the platinum material is loosened from the stainless steel thin-wall pipe. Therefore, a pure platinum needle water electrode structure capable of ensuring the connection reliability of the platinum needle and the electrode body and having excellent sealing performance is required.
