Abstract

The utility model provides an electric filter reactor with a copper pipe circulating water internal cooled coil. The utility model has the structure different from existing iron core or hollow filter reactors that the coil adopts a hollow copper pipe to replace an original solid copper and aluminum conducting wire in order to effectively reduce the temperature rise of the coil, and the cooling mode is a copper pipe internal circulating water cooled mode which can be used for iron core or hollow electric filter reactors. The specification 1 is a three-phase iron core electric filter reactor. Disclosed in the specification, the utility model comprises a copper pipe coil pack 1, a water inlet or a water outlet of a copper pipe coil 2, a wiring copper bar 3 of the copper pipe, an iron core post 4, an iron yoke 5, a channel steel for clamping the iron yoke 6, a stainless steel tightness adjusting screw rod 7, a stainless steel screw for clamping the iron yoke 8, a base 9, a coil space block 10, an insulating sleeve 11 of the screw for clamping the iron yoke, an upper channel steel for pressing the iron yoke 12, a board for clamping the iron core post 13, an air gap padding 14 between an iron core and the iron yoke, an insulating board 15 and a copper pipe coil former 16.

Description

Coil is the electric filtering reactor of copper pipe recirculated water inner-cooled

(1) technical field: the utility model technical field of electricity particularly relates to the filter reactor in a kind of power filter device.

(2) background technology: the filter reactor in the existing power filter device mainly contains two kinds of hollow, iron cores: the hollow filter reactor is made of coil, coil holder; Iron core reactor is made of coil, the closed magnetic circuit iron core that air gap is arranged and coil holder combination.Its coil is copper, the aluminum conductor of real core, its cooling means be air and oil cooling but.Because the electric current that flows through in the filter reactor also has sizable harmonic current except that fundamental current, what have surpasses the fundamental current several times, and the heat that harmonic current produces in coil is more serious than fundamental current, and therefore, the temperature rise of filter reactor coil is very high.In order to reduce temperature rise, adopt the current density that reduces lead usually, increase the area of dissipation of coil, but increased lead consumption, strengthened volume, weight and the cost of filter reactor.

(3) summary of the invention: higher and lead consumption is too much in order to overcome existing filter reactor coil temperature rise, the deficiency that volume, weight and cost are bigger than normal, the utility model provides a kind of filter reactor can effectively reduce coil temperature rise, reduce the winding wire consumption, dwindle filter reactor volume, weight and reduce its cost.

The technical scheme that its technical problem that solves the utility model adopts is: coil replaces copper, the aluminum conductor of original real core with copper pipe, the type of cooling is recirculated water cooling in the copper pipe, low pressure (being no more than 1000 volts) filter reactor particularly, recirculated cooling water does not need special processing, can satisfy the electric insulation requirement.

The beneficial effects of the utility model are effectively to reduce coil temperature rise, reduce the winding wire consumption, dwindle filter reactor volume, weight and reduce its cost.

(4) description of drawings:

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is that coil is the tri-phase iron core electric filtering reactor example of copper pipe recirculated water inner-cooled; Fig. 2 is the I-I profile of Fig. 1.

Among the figure: 1. copper tube coil bag (interior is copper pipe, binder, insulation spacer etc.); 2. the water inlet of copper tube coil or delivery port; 3. the copper busbar of copper tube coil; 4. iron core column; 5. iron is gripped; 6. the iron yoke clamps channel-section steel; 7. stainless steel tightens screw rod (containing pad, packing ring, nut); 8. stainless steel and iron yoke pinching screw (containing pad, packing ring, nut); 9. base; 10. coil cushion block; 11. the insulating sleeve of iron yoke pinching screw; 12. upper yoke compresses channel-section steel; 13. iron core column clamping plate; 14. air gap bedding and padding between iron core and iron yoke; 15. insulation board; 16. copper tube coil skeleton.

(5) embodiment:

Fig. 1 is that coil is the tri-phase iron core electric filtering reactor example of copper pipe recirculated water inner-cooled; Fig. 2 is the I-I profile of Fig. 1.(interior be copper pipe to copper tube coil bag among the figure, binder, insulation spacer etc.) (1), the water inlet of copper tube coil or delivery port (2), the copper busbar of copper tube coil (3), iron core column (4), iron is gripped (5), the iron yoke clamps channel-section steel (6), stainless steel tightens screw rod and (contains pad, packing ring, nut) (7), stainless steel and iron yoke pinching screw (contains pad, packing ring, nut) (8). base (9), coil cushion block (10), the insulating sleeve (11) of iron yoke pinching screw, upper yoke compresses channel-section steel (12), iron core column clamping plate (13), air gap bedding and padding (14) between iron core and iron yoke, insulation board (15), copper tube coil skeleton (16), press the usual way combination, be not both with existing filter reactor: the copper that replaces original real core with copper pipe, aluminum conductor, the type of cooling is for cooling off by recirculated water in the copper pipe, can effectively reduce coil temperature rise, reduce the winding wire consumption, dwindle the filter reactor volume, weight and reduce its cost.Low pressure (being no more than 1000 volts) filter reactor particularly, recirculated cooling water does not need otherwise processed, satisfied the electric insulation requirement, therefore, this novel filter reactor suits especially in the occasion that possesses the recirculated cooling water condition, as: the filter reactor in the power filter device of middle frequency furnace etc.

The utility model can be used for iron core, hollow electric filtering reactor.

Claims

1, the filter reactor in a kind of power filter device is characterized in that: coil substitutes copper, the aluminum conductor of original real core for the hollow copper pipe, and cooling means is recirculated water cooling in the coil.
