4.4 Test under single fault conditions

4.4.1 Overview It should be according to the following requirements.

a) Check the device and circuit diagram can usually determine whether there is likely to cause dangerous fault conditions and therefore whether it should be applied.

b) In addition to proof of a specific fault conditions likely to cause danger, the test shall be made by the fault, or select test Alternative method of compliance prescribed in place of fault testing [see GB 4793.1-2007 of 9b) and 9c)].

c) device should work under reference test conditions (see 4.3) the most unfavorable combination of conditions, for different faults, these combined conditions You can vary the combination of these conditions should be recorded during each test.

4.4.2 Fault conditions imposed Fault conditions 4.4.2.1 ~

4.4.2.7 should include provisions for fault conditions. These fault conditions can only be applied to one and should press Sequentially applied in any convenient order, can not be applied more than one fault at the same time, the results unless it is applied to a fault caused by a fault. After each applied once the fault condition, equipment or parts shall pass the applicable test 4.4.4.

4.4.2.1 Protective conductor Protective conductor should be disconnected, but permanently connected devices or comply with GB/T 11918 ~ GB/T 11919 of the connector is provided Preparation excluded.

4.4.2.2 short-time or intermittent operation of equipment or components If the single fault conditions can cause these devices or components for work, it should make it work continuously. The individual zero Member includes motors, relays and other electromagnetic devices.

4.4.2.3 Motor Motor should stop it or prevent it from starting when fully energized and choose one of the more disadvantaged.

4.4.2.4 Capacitors Motor auxiliary winding circuit capacitor (except for self-healing capacitors) should be short-circuited.

4.4.2.5 Power Transformers The secondary winding of the power transformer should be required to 4.4.2.5.1 will be short-circuited, according to the provisions of 4.4.2.5.2 it is overloaded. at a Test damaged transformer, allows for repair or replacement before the next test. 4.4.2.5.1 Short circuit Each and every part of the output winding tapped output winding taps without load connected during normal use should turn again Test, a test to simulate a load short circuit. Test overcurrent protection device remains in place, all other windings connected to the load or no load connected, Select the loading conditions of normal use of the more disadvantaged. 4.4.2.5.2 Overload Each part of the output of each winding is not tapped and tapped output winding overload test shall be carried out sequentially, a first test A. Other windings are connected to load or not load, select a load of normal use of the more disadvantaged. If the fault condition test

4.4 Any overload, the individual secondary windings should bear those overloaded. On winding connected across a variable resistor overload test. Resistor adjust as quickly as possible, if necessary, in 1min After re-adjust to maintain the applicable overload. After allow no further adjustment. If the current interrupting device to provide protection, the overload test current of overcurrent protective device can be turned on just 1h maximum current. Before the test, the protection device can be negligible impedance connection instead. If the test current value can not be obtained from the normative protection device, then To be determined by experiment. When the design to achieve the required output voltage overload disappears equipment overload slowly increased, reaching just cause the output power The disappearance of the overload point pressure overload front of a point. In all other cases, the overload is the maximum output power from the transformer can be obtained. Having to meet GB transformer overtemperature protection requirements 4793.1-2007 14.3, during the short-circuit tests 4.4.2.5.1 no longer Withstand overload test. 4.4.2...
