[0003] The current test method is manually transferred by the operator, which is cumbersome and frequent, takes up manpower and is not efficient
The operation of mutual conversion can be easily realized through the programmable logic controller (PLC), but because there are only two control points, the above operations through the PLC controller need to be equipped with a set of equipment such as the PLC controller and IO board, which is economical Poor sex

The invention discloses a current switching device for detecting the life of a sodium-sulphur battery electrolyte ceramic tube in the field of energy storage. According to the current switching device, a first contactor KM1 and a second contactor KM2 which are closed and opened in turns are arranged between a sodium-sodium battery and an external charge-discharge device, the direction of a charge current for charging the sodium-sodium battery by the external charge-discharge device is switched to enable the charge current to switch between the two states of flowing to the negative pole of the sodium-sodium battery from the positive pole of the sodium-sodium battery, and flowing to the positive pole of the sodium-sodium battery from the negative pole of the sodium-sodium battery. The technical effects are as follows: the switching of the current direction can be realized in detection for the life of the sodium-sulphur battery electrolyte ceramic tube according to the changes of the current, and the test working of detection for the life of the sodium-sulphur battery electrolyte ceramic tube is automatically finished by matching with the working of the external charge-discharge device, thus saving labour and increasing efficiency.
Description
technical field [0001] The invention relates to a current switching device for life detection of a sodium-sulfur battery electrolyte ceramic tube in the field of chemical energy storage. Background technique [0002] In the sodium-sulfur battery test, in order to test the performance of the electrolyte ceramic tube, a sodium-sodium battery test is used in which the positive and negative electrodes are sodium elements. Because the material of the positive and negative electrodes is the same, the sodium-sodium battery does not have the characteristics of ordinary batteries. It cannot be tested by charging and discharging. It can only be charged from the positive electrode to the negative electrode, and then turn the charging power cord to continue charging from the negative electrode to the positive electrode. That is, discharge, switch once every hour, and cycle operation. [0003] The current test method is manually transferred by the operator, which is cumbersome and frequ...
