The potentiostat is said to be a negative feedback amplification-output system, which is closed-loop regulated with the protected object (such as buried pipeline). The potential of the energization point is measured by the reference electrode, and the sampling signal is compared with the control signal to achieve control. The polarization current output is adjusted so that the potential of the energization point is maintained at the set control potential.
What is a potentiostat?
The potentiostat itself is a branch under a rectifier with constant potential and constant current function.
Constant potential refers to the reference electrode feedback as a constant standard to control the output of the finisher.
Very simple, for example, a newly built pipeline, the cathodic protection potential requires -1.2V, then the potentiostat given potential is set at -1.2V, then the potentiostat is increased in order to achieve the -1.2v requirement. Until the potential is -1.2V. At this time, the output voltage is 10V, for example, 5A, then we can say that this pipeline meets the protection requirements, the required voltage is 10V, and the required current is 5A.
If there is a problem with the constant potential, such as interference, reference electrode damage, etc., how does the potentiostat work?
At this time, a constant current function is required, and a constant current output, that is, the current output does not change, and the voltage changes. Or the last example, if the constant potential is damaged, how should I set the constant current? We learned from the previous paragraph that the current required by this pipeline is 5A. In this case, we should set the constant current to 5A. To the test pile, use the portable reference to measure the true potential of the pipe under -1.2v. If it is, then it is suitable to give 5A. If it is small, add some current. If it is big, it will reduce the current. This is people. Often said to run manually.
What is the concept of a rectifier?
A rectifier is a device that converts alternating current into direct current.
One must be active in the market according to the rectification method, that is, you can see 1 thyristor rectification (thyristor rectification). Features: simple, tidy, easy to operate, easy to maintain. 2 high frequency switching rectification. Features: light weight, small size, various forms (vertical, desktop, wall hanging, etc.), easy installation and maintenance, simple operation, high efficiency and energy saving, high control accuracy, high anti-interference ability, strong adaptability of the power grid. 3, explosion-proof rectification features: high degree of componentization, stable performance. 22 The majority of thyristors in the market, high-frequency switching technology has matured and there are many adopt this form.
