Dc motor dc motor debugging is in intensive test, confirm the equipment under the premise of its function of maintenance equipment. This kind of test function basically is to ensure that all equipment is in the scope of the specification. Registered equipment manufacturers generally said that has test performance. The certification of equipment, but, dc motor repair and debugging, testing content and more. Registered equipment check to see if the devices have a fit, there are three important for certification test equipment. These include: 1. Field validation maintenance function set in this test, using the smaller voltage, frequency and current system introduced in the test run results. In the operation of the equipment, record and view. 2. Island effect in this test, the load added cohesion breaking point of view. At the same time delay after the restart. 3. The exported functions in this test, the device adopts reverse power or reduce the power equipment running test. Not certified equipment certification test, perform the following tests in order to make sure it is safe in the industrial production must system arrangement: 1. Function test of this type of test is to look at whether the composition, the desired way. Be part of the cover may be different from the process and the industry. Below the main activities include: dc motor test equipment and the function of the voltage level of the above test above and below the equipment of dc motor frequency level of dc motor function test equipment can strengthen the dying. Test of time, need stability in the device to restart the system fault detection,If applicable)Synchronous control test (If applicable)Test the island and the exported functions (If applicable)2. Check the equipment setup device to check, if the above test, specification of equipment validation is in accordance with the relevant provisions. 3. Trip test this test to ensure the equipment damage of protective equipment placed the normal work of the circuit. Model test reverse power operation conditions, after the introduction of variable function parameters. Interlock circuit with insert device test, verify whether they fit specifications, they are right or wrong. 4. The test is to help test for normal operation of the guarantee system of the circuit. Wiring to complete the view, current, polarity, the direction of the line, CT/PT, etc. The size of the voltage, current and induction, power, frequency and the phase Angle parameters and system analysis correctly.
