Description
Technical field
The utility model relates to a kind of instrument transformer and draws type secondary connection box, belongs to instrument transformer manufacturing technology field.
Background technology
Existing rated voltage is the 66-110KV electromagnetic potential transformer, normally base designs is become a kind of circle, draws the inner secondary outlet of instrument transformer through little porcelain vase, is not easy operation during use; Little porcelain vase is exposed in the air, makes moist easily, causes Jie's damage of product to exceed standard; After transportation was jolted, the seal on the little porcelain vase possibly be shifted, and causes leakage of oil; Little porcelain vase is frangible, and antitorque pressure ability is when its work; The excessive porcelain vase that causes easily of exerting oneself is cracked, influences the normal use of product, and do over again and the after-sale service increase meeting of product bring bigger financial burden to enterprise.
The utility model content
The purpose of the utility model provides a kind of a kind of electromagnetic potential transformer secondary connection box of simple in structure, good sealing effect.
To achieve these goals, adopt following technical scheme: a kind of electromagnetic potential transformer secondary connection box is characterized in that: said terminal box comprises upper plate and the lower shoe that connects through bracing frame; Have link on the upper plate, and have lead entering hole on the upper plate, the below of upper plate is connected with L shaped pipeline; The top and the upper plate of L shaped pipeline are tightly connected, and the upper opening of L shaped pipeline gets into the hole with lead and is communicated with, and the lower openings of L shaped pipeline is provided with first flange; Protective cover is fixed through first flange and L shaped pipeline; Terminal block in the protective cover is connected through bolt seals with first flange, and conducting rod passes first flange and terminal block, and conducting rod one end is positioned at L shaped pipe interior; The other end is positioned at protective cover, and the wall of protective cover bottom is provided with lead and picks out the hole; Also be connected with on the L shaped pipeline lower pipeline and have the plug cock joint that pin type is got fuel tap through tube connector.
In order to guarantee sealing effectiveness, two sides that said terminal block is relative with first flange are provided with the seal groove with sealing ring.
Support for ease, the bottom of said lower shoe is provided with the back-up block that has hole for hoist.
For the ease of fixing, the upper surface of said lower shoe is provided with the ground plate that is used for fastening earth stud.
Seal cover is connected through bolt with second flange on the protective cover, makes seal cover, protective cover and first flange form a closed cavity.
The utility model is through improving the secondary line outlet for drawing the type structure; Can be effectively that secondary line and air is isolated, simple in structure, easy to operate, can greatly increase work efficiency; Because secondary line is immersed in the transformer oil in the pipeline; Jie of product is decreased receive air influence, can improve more than the product percent of pass to 99%, solve effectively that existing protection against the tide, anti-leakage of oil, fuel-economizing, operating efficiency are low, stability and less economical problem.
