继电器寿命试验机是根据标准IEC60950-1 第2.8.7.2及2.8.2.3节要求设计制造而成
IEC60950-1标准要求:
2.8.7.2 Overload test
The contact of a switch or relay in the SAFETY INTERLOCK system is subjected to an overload test consisting of 50 cycles of operation at the rate of 6 to 10 cycles per minute, making and breaking 150 % of the current imposed in the application, except that where a switch or relay contact switches a motor load, the test is conducted with the rotor of the motor in a locked condition. After the test, the SAFETY INTERLOCK system, including the switch or relay, shall still be functional.
2.8.7.3 Endurance test
The contact of a switch or a relay in the SAFETY INTERLOCK system is subjected to an endurance test, making and breaking 100 % of the current imposed in the application at a rate of 6 to 10 cycles of operation per minute. A higher rate of cycling is permitted if requested by the manufacturer. For reed switches used in SAFETY INTERLOCK systems located in ELV CIRCUITS, SELV CIRCUITS and TNV-1 CIRCUITS, the test is 100 000 operating cycles. For other switches and relays in SAFETY INTERLOCK systems, the test is 10 000 operating cycles. After the test, the SAFETY INTERLOCK system, including a switch or relay, shall still be functional.
