Abstract
The utility model relates to a high-voltage dry metering tank which comprises a stainless steel tank body, a voltage transformer and a current transformer. Five high-voltage wiring terminals of phase A, phase B and phase C are arranged on the stainless steel tank body and sleeved with high-voltage ceramic sleeves, the high-voltage wiring terminals, the voltage transformer and the current transformer are correspondingly connected with one another respectively to form a transformer combination, and the transformer combination is integrated by outdoor epoxy resin in a vacuum casting manner. Due to the transformer combination integrated by the outdoor epoxy resin in the vacuum casting manner, insulating oil failure checking is omitted, maintenance expenses are saved greatly. The high-voltage dry metering tank is small in size, is light, and can be mounted in any direction and run without maintenance for a long time as compared with a conventional oil-immersed metering tank.
Description
Technical field
The utility model relates to a kind of high pressure dry batch meter.
Background technology
Existing High-voltage measuring box is in the majority with old-fashioned oil immersed type batch meter; The oil immersed type batch meter has shortcomings such as bulky, heaviness, especially need regularly carry out the insulating oil failure detection; The human and material resources of palpus labor carry out plant maintenance, have increased the cost of electric power unit of operation.
Summary of the invention
The purpose of the utility model is to overcome the defective of prior art, provides a kind of and need not insulating oil, is convenient to the high pressure dry batch meter of installation and maintenance.
For realizing above-mentioned purpose; The utility model adopts a kind of like this high pressure dry batch meter; Comprise stainless steel casing, voltage transformer (VT) summation current transformer, described stainless steel casing is provided with A, B, 5 high tension terminals of C three-phase, and described high tension terminal is with high voltage porcelain bushing outward; Described high tension terminal and described voltage transformer (VT), the corresponding respectively combination transformer that connects and composes of described current transformer, described combination transformer is poured into an integrated entity by outdoor epoxide resin vacuum.
Especially; Described high pressure dry batch meter also is provided with active electric energy meter and reactive energy-meter; The secondary side output of described combination transformer is connected to described active electric energy meter and described reactive energy-meter respectively through the low pressure terminal box; The described stainless steel casing outside is provided with seal closure, and described seal closure holds described low pressure terminal box.
Especially, the below of described stainless steel casing is provided with the installation base plate, and the outside of described stainless steel casing is provided with earth stud.
Compared with present technology, the utility model adopts the combination transformer that is poured into by outdoor epoxide resin vacuum, need not carry out insulating oil inefficacy inspection, has practiced thrift maintenance cost widely.It is little, in light weight to the utlity model has volume, compares oil immersed type batch meter in the past, but any direction is installed long-term non-maintaining operation.
