在畜牧场里,保证安全用电是牧业生产电气化的一个必要条件。为了正确的使用保护设备,必须知道对人、畜的安全电流和电压。 直接作用于生命组织的电流,要引起生物体的物理(灼伤)、化学的或机械的损伤。这种作用通常是在大电流(几十安培)的作用下才发生,而毫安级的小电流则通过神 In livestock farms, ensuring safe use of electricity is a necessary condition for the electrification of animal husbandry. In order to properly use the protective equipment, you must know the safety of people and livestock current and voltage. Directly acting on the living tissue current, to cause physical (burns), chemical or mechanical damage. This effect usually occurs at a high current (tens of amperes) while a small milliamp current passes through the gods
