Description
Technical Field
The utility model relates to a transformer technical field, concretely relates to low pressure transition copper bar bearing structure in protection casing.
Background
Along with the user to transformer protection and safety consciousness's attention, the transformer all requires to take the protection casing structure usually, and high-low voltage cable all adopts inlet wire under the high pressure, and outlet wire structure under the low pressure inserts the transformer bushing through drawing down the sealed cable head of protection casing, and such structure can be rain-proof dustproof, also can prevent the toy, prolongs the life of transformer annex, still can prevent to electrocute simultaneously, ensures safe power consumption.
And large capacity transformer, it is great because of low pressure side electric current, the transition copper bar cross-section also can increase, and some two copper bars of needs are parallelly connected to be drawn forth, lead to the transition copper bar quality can be very heavy, if support the transition copper bar firmly inadequately, vibrations during the transformer operation can make the copper bar rock to lead to the low pressure connector lug not hard up, light then transformer oil leakage, heavy then low pressure side generates heat and leads to the transformer to burn out.
