请帮忙把以下这段话翻译成英语

Test, to switch to 1.5 times through maximum rated current 220A, rated voltage switch 450V level, switch resistors according to actual use situation in tap-changer will install buried in the resistor thermocouple respectively and points below, switch 20mm not less than the actual operation according to the mechanism of uninterrupted speed continuous, 6 times, each are switching to its highest temperature records, after the test should not be more than 300K temperature.
仅供参考

The testing time , leading to the switch with 1.5 are maximal fixed pass 220 voltaic As, before fixed switch level voltage be in progress under 450 V, the switch electrical resistor uses condition installation to bury the place being set up in the electrical resistor and not being smaller than on measurement point down part 20 mms respectively in tap changer Lieutenant General electric thermo-couple according to reality, continuation the actual switch operation speed according to electric organization
