The safety performance of 4 type ZHZ36A (electrical safety) integrated test system The working principle of the system frame
Test system principle
Principle of the test system. This system is composed of a cabinet, the first layer PC40A Digital insulation resistance tester, the second layer is PC39A Digital ground resistance tester, the third layer is PA30 Digital leakage current tester; the fourth layer is ZHZ8 High voltage tester. The tester by digital display value of insulation resistance and grounding test current value and the value of grounding resistance, leakage current value and the test voltage value, and withstand test voltage value. The tester can operate independently and single measurement, but also combined operation. The bottom cabinet test switch control circuit.
The safety performance of 5 type ZHZ36A (electrical safety) integrated test system Operation method :
Five point one In the connection, this test system and test box grounding clip correctly connected with the test system.
Five point two The power switch is in the "all instruments open" position, open the power switch controller, each test system includes a controller of the power supply part are connected, the power indicator light.
Five point three In the object to be measured under the condition of complete set value of each tester preset according to the requirements. (see the use of tester instructions )
Five point four The test socket of the measured object the power plug into the test line of the test system in the box, the test system grounding clip to the measured grounding point indication (the grounding point indication by the user according to the measured test requirements).
Five point five According to the requirements of the selection of test items button.
Five point six Connect the line carefully check the analyte and the test system is accurate, can press the "start" button, then the test system according to the required test items and test conditions. After the end of each test , You must press the "reset" button, select the other test items button, then press the "start" button can be carried out under a test. In the process of measurement , Do not press any button.

Eight Comprehensive testing system of safety rules for safe operation of electrical appliances
Eight point one The staff must be familiar with the test system operating procedures , Can be used.
Eight point two The operation of Taiwan around required the laying of high voltage insulation rubber.
Eight point three Turn on the power supply before every day , Carefully check each test line and test kit and test whether the loosening of the grounding clip.
Eight point four The test clamp shall not be arbitrarily placed , When not in use and may not be the test cabinet and the earth system , To prevent the misuse of the test instrument is broken.
Eight point five After the boot power , We should check the set position switch, the test button and pressure regulator carefully.
Eight point six Press " start-up " Button , Not to adjust the whole test system and other test button contact line and the measured object.
Eight point seven After the end of the testing process , Need to press the "reset" button to remove the test line.
Eight point eight At the end of the testing process , Whether the result qualified or unqualified , They need to press the "reset" button to reset the system , Otherwise the system for the next test phase response. Such as the discovery of abnormal test system , Can also press the "reset" button or shutdown to suspend the whole system test , To restore after the restart test.
Eight point nine In order to ensure the accuracy of the test voltage, AC power supply and power output suggest user configuration matching. If you need to test the function of the test system is working properly, the user can select" ZHZ36 Integrated test system type electrical safety performance simple calibration device for routine simple diagnosis.
