Intracavitary is equipped with iron core.Primary Conductor cast is encapsulated in an epoxy resin shell, and sealing forms primary conductive part.Two one
Secondary connecting terminal components are symmetrical arranged, and the Primary Conductor retaining ring on two primary connection terminal assemblies, which is respectively sleeved at, once to be led
The both ends of body, Primary Conductor retaining ring and Primary Conductor are locked by a terminal block clamping screw.
Secondary coil unit, including secondary coil and two secondary output terminals, secondary coil cast are encapsulated in two secondary rings
In oxygen resin-case.Two secondary output terminals are connect with two leads of secondary coil respectively.Multiple secondary coil units
Secondary coil is set on an epoxy resin shell of primary insulation guide rod.Positioned at the both ends of multiple secondary coils, primary
The both ends of epoxy resin shell are arranged with two sub-cell fixed rings respectively.In the secondary output terminals of multiple secondary coil units
Join piece equipped with the first secondary remittance connection piece and second secondary remittance.First secondary wherein one converged on connection piece and each secondary coil unit
A secondary output terminals connection, second secondary another secondary output terminals converged on connection piece and each secondary coil unit connect
It connects.It is respectively equipped with a secondary remittance townhouse outlet terminal in the first secondary remittance connection piece and second secondary one end for converging connection piece.
Multiple secondary coil units are in parallel, and total capacity is equal to the product of single coil capacity and coil number, passes through secondary line
The suit number and type of coil unit can realize that the amount of capacity of secondary remittance townhouse output is adjustable, also can adjust single secondary coil
The type of unit keeps class of accuracy and no-load voltage ratio variable.Pass through the primary of the terminal connections row on a connecting terminal after being completed
Terminal block mounting hole is connected and fixed with a main circuit.
Type of device：It is indoor
Current transformer part individual unit accuracy class：0.2S/0.5/10P electric current ratios：300-600/5A
Individual unit output capacity：10/10/15VA frequencies：50/60Hz
Electric current monomer standard metaplasia is produced, and is assembled by on-site actual situations；One chip current transformer；Primary conductive part can
It is produced by cabinet dimensional structure；Capacity can be combined by actual conditions.
It the advantage is that：This type product takes combine design that can carry out increase and the winding element of capacity according to demand
Reconfigure, can be standardized with unit, be asked convenient for quickly meeting onsite application in process of production, when production can be by standard
Metaplasia is produced.
