Abstract
A current mutual inductor used for high-pressure soft boot of a light rail comprises a primary winding, a secondary winding and a shell body. The secondary winding is arranged on an iron core in a winding mode. A high-precision direct-current resistor is connected on the secondary winding in series. The primary winding is an annular electric conductor. The primary winding penetrates through the iron core. Two leads of the primary winding are respectively connected with a primary wiring board. After being laid, the primary winding and the secondary winding are poured into an integrated structure in a vacuum mode with epoxy resin, wherein an epoxy resin poured body is the shell body. Three leads of the secondary winding are respectively connected with three secondary wiring terminals of a secondary wiring board on the upper end face of a base in a corresponding mode. The shell body is fixed on the base through sealing bolts. The current mutual inductor used for high-pressure soft boot of the light rail is small in size, good in heat dissipation effect, resistant to dirt and humidity, strong in flexibility, convenient to install and stable in performance.
Description
Technical field
The utility model belongs to the electrical installation field, relates to a kind of novel power saving device for 10KV electrical power trans mission/distribution system and enterprise, particularly light rail high pressure soft starting Current Transformer.
Background technology
Along with China's rapid development of economy, light rail has become the quick means of transportation of traffic, traditional instrument transformer is specially joined the link of transducer or current transducer output signal by the centre, like this, carry the accuracy of signal very unstable, in addition, the shared space of traditional product is bigger, and middle process is numerous and diverse, be not suitable for quantizing to produce, and corrosion resistance is low, damages easily often, influences operate as normal, very difficult on the heat radiation link during work, outside first, the voltage output value instability of traditional instrument transformer, and inaccurate.
The utility model content
The purpose of this utility model provides light rail high pressure soft starting Current Transformer, and this instrument transformer precision height is corrosion-resistant.
The technical scheme that adopts is:
Light rail high pressure soft starting Current Transformer comprises winding, secondary winding and housing one time;
The secondary winding winding is in series with the high accuracy D.C. resistance on the secondary winding on iron core; A winding is annular electric conductor, and one time winding passes iron core, and two lead-in wires of a winding are connected (see figure 1) with primary connection plate P1 with P2 respectively; Winding and secondary winding are laid good back and are poured into an overall structure with epoxide resin vacuum, wherein epoxy resin poured body is housing, three lead-in wires of secondary winding respectively be arranged on the base upper surface on corresponding three secondary connection terminals of secondary connection box connect, housing is bolted on the base by capping.
The utility model is that epoxide resin vacuum is poured into a mould totally-enclosed column support type structure, adopt the high accuracy D.C. resistance of import and put outer hidden mode, belong to full operating mode product, adopt the cast of polymer inlet mixed fillers, good heat dissipation, resistant is turbid and moist, and survey bureau's value of putting is not higher than 5PC under the 14.4kV magnitude of voltage, voltage output signal error amount is less than 0.2%, and the class of insulation reaches B level 90 degree.
Advantage of the present utility model is:
The utility model volume is little, good heat dissipation, and resistant is turbid and moist, for 50Hz; do electric current, electric energy measurement and relaying protection in the 10kV power circuit and use, current signal and the voltage signal of instrument transformer are exported simultaneously, satisfy the high requirement of precision; and flexibility is strong, and is easy for installation, stable performance.
