Abstract
The utility model relates to an electrostatic precipitation transformer, aiming to resolve technical problems that the existing electrostatic precipitation transformers are high in transient current and release heat when in short circuit, can form electric arc, are easy to burn out afterward equipment such as electrostatic precipitators, generate heavy impaction on the electrostatic precipitators and affect performances thereof, and even damages transformers. The electrostatic precipitation transformer is arranged in a tank body (5) which contains transformer oil, and comprises a transformer coil (1), an iron core (2), a rectifier (3) and a reactor (4), wherein the reactor (4) is a non-magnetic hollow coil serially connected in an output circuit of the rectifier (3). The electrostatic precipitation transformer can inhabit short circuit current, reduce heat release and increase arc extinguishing capacity, and then effectively protects the electrostatic precipitation transformer and the afterwards electrostatic precipitator and the like.
Description
Technical field
The utility model relates to a kind of electrostatic dust collection equipment, specifically a kind of electrostatic precipitation transformer.

Summary of the invention
The immediate current that existing electrostatic precipitation transformer produces when the short circuit is big in order to solve, the heat height that discharges, also can form electric arc; connect equipment after burning out electrostatic precipitator etc. easily; and electrostatic precipitation transformer itself produced enormous impact, influences its performance even damage the technical problem of transformer, thereby the utility model provides a kind of suppresses short circuit current, the heat that reduces to discharge, strengthen the electrostatic precipitation transformer of the equipment such as electrostatic precipitator that connect after arc performance effectively protects electrostatic precipitation transformer itself to reach.
The utility model is solved by the following technical programs:
The electrostatic precipitation transformer, described electrostatic precipitation transformer is placed in the casing, fill transformer oil in the casing, described electrostatic precipitation transformer comprises transformer coil, iron core and rectifier, also comprise reactor, reactor is connected in the outlet line of described rectifier for the air core coil of no magnetic conduction.The reactor owing in the high-voltage output line road of rectifier, connected, when being short-circuited, voltage drop on the reactor is bigger, played the effect that electric current changes that suppresses, the heat that reduces to discharge, enhancing arc performance, thereby reduce to electrostatic precipitation transformer itself and after the impact of the equipment such as electrostatic precipitator that connect, the equipment such as electrostatic precipitator that connect after effectively protecting electrostatic precipitation transformer itself to reach; Reactor adopts the air core coil of no magnetic conduction, and its inductance is bigger, and the magnetic field of generation is stronger, has the effect of stronger inhibition short circuit current; The electrostatic precipitation transformer is placed in the casing, make transformer coil, iron core, rectifier and reactor all be immersed in the transformer oil, not only can improve the dielectric strength between the above-mentioned parts, and can strengthen the heat dispersion of static transformer, also have good extinguishing arc effect.
Above-mentioned electrostatic precipitation transformer, described reactor is composed in series by plural air core coil.By the reactor that plural air core coil is composed in series, when running into short-circuit impact, its shunting effect is better, and the also easier quilt of the heat of generation disperses.
Above-mentioned electrostatic precipitation transformer, described reactor are fixed on by insulator on one's body the device of electrostatic precipitation transformer.The structure of this electrostatic precipitation transformer is simpler, assembles also more convenient.
Above-mentioned electrostatic precipitation transformer, the device of described electrostatic precipitation transformer is as the fixed clip of iron core.
Above-mentioned electrostatic precipitation transformer, the screw rod that described insulator is made for the epoxy plate material.
Above-mentioned electrostatic precipitation transformer is provided with two above taps on the described transformer coil.Tap is set on transformer coil, can adjusts the output voltage of rectifier by the number of turn that changes the transformer coil in the place in circuit.
Above-mentioned electrostatic precipitation transformer, described rectifier are bridge rectifier.
The utility model is because the reactor of having connected in the high-voltage output line road of rectifier, so thereby can suppress short circuit current, the heat that reduces to discharge, strengthen the electrostatic precipitation transformer of the equipment such as electrostatic precipitator that connect after arc performance effectively protects electrostatic precipitation transformer itself to reach.

Embodiment
Below by embodiment the utility model is described in further detail:
As shown in Figure 1, 2, the electrostatic precipitation transformer comprises transformer coil 1, iron core 2 and rectifier 3, and described rectifier 3 is a bridge rectifier, series reactor 4 in the high-voltage output line road of rectifier 3; As shown in Figure 2, reactor 4 is composed in series by the air core coil of two no magnetic conductions, and three tap X1, X2, X3 are set on the described transformer coil 1.
As shown in Figure 3, transformer coil 1, iron core 2, rectifier 3 and reactor 4 all are placed in the casing 5, fill the transformer oil (not shown) in the casing 5, roller is equipped with in bottom at casing 5, can easily the electrostatic precipitation transformer be transported to erecting yard, the best strap brake positioning function of roller, the location when both being convenient to the electrostatic precipitation transformer is installed, moving after also being convenient to complete.Because the heat that produces during the transformer operation can make the transformer oil expanded by heating, therefore the transformer oil in the described casing 5 can not be filled; Reactor 4 is fixed on by the screw rod (not shown) on the fixed clip 6 of iron core 2, the insulator that described screw rod is made for the epoxy plate material.
In a word, the above only is preferred embodiment of the present utility model, and all equivalent variations and replacements of being done according to the utility model architectural feature all should belong to covering scope of the present utility model.
