Literature search through prior art is found, Chinese patent application number is 95209200.X, the utility model name is called: the resin-insulated dry iron core shunt reactor, this patent readme is: " a kind of iron core shunt reactor of mainly forming; the last lower yoke of iron core is used the folder from top to bottom clamping respectively; the stem of iron core is to be overlapping and the clamping plate clamping is arranged by a plurality of discuses and gap-gas segregating ring, is connected with ground strip between the discus by unshakable in one's determination and coil; Pad is placed between folder and the coil, it is characterized in that: the discus outer surface has one deck resin-encapsulate layer, and whole stem appearance has resin composite body, and outer surface unshakable in one's determination has one deck resin-encapsulate layer; Be resin composite body between the surfaces externally and internally of coil, upper and lower end parts and the conductor, the side surface of coil has fixing outlet terminal; Insulator is fixed on the folder; Dismountable and have the lead-in wire of insulating coating to connect outlet terminal and insulator." but this shunt reactor still can't solve the above problems, and has still that vibrations are big, noise is high, iron is gripped problems such as high material consumption.
Summary of the invention
The utility model provides a kind of Chinese character pin-shaped iron core shunt reactor at the deficiency that prior art exists, and makes that it can realize 3 phase magnetic circuit balances, vibration is little, noise is low, iron grips that material consumption is few, loss is little, cost is low moves targets such as more safe and reliable.
The utility model is achieved through the following technical solutions, the utility model comprises up and down that iron is gripped, three-phase stem, three coils, folder, annexation is: iron is gripped up and down, the three-phase stem forms unshakable in one's determination, last lower yoke is used the folder clamping respectively, more than, the lower yoke center circle center of circle is benchmark, angle is that 120 ° of directions are arranged on down iron in a triangle and grip between the three-phase stem, and three coils are enclosed within respectively on the three-phase stem.
Described coil, its each by structure independently some mounting coils constitute, the lifting one's head of some coils behind the suit externally connects after drawing, and can connect or directly connection by insulator.
Described three-phase stem, its surface adopt ground connection screen uniform electric field, and compress by disk spring.
Described three-phase stem, its inner discus adopts traditional radiant type or laminated structure.
Described upper yoke is pressed on the three-phase stem.
Described iron is up and down gripped and is adopted the silicon steel sheet coiling to form.
Described iron core, folder are connected with the pressure frame, press between frame and the reactor base elastic rubber fitting is set.Iron core, folder, base and pressure frame are fastenedly connected.
Described pressure frame is between iron core and elastic rubber fitting.
The head end of three coils of the utility model is received A, B, the C phase of three-phase power circuit respectively, and the end of three coils ground connection that connects together is in order to the capacitance current of compensated line.Because the three-phase stem has adopted " product " font structure, can keep the three-phase magnetic circuit balance, cooperate above-mentioned loop construction simultaneously and press frame, can solve better that vibrations are big, noise is high, iron is gripped problems such as high material consumption, improve the fail safe and the reliability of operation.
Compared with prior art, the utility model vibrations are little, noise is low, iron is gripped advantages such as material consumption is few, loss is little and cost is low, security of operation.The utility model changes traditional " one " font structure into " product " font structure, simultaneously with coil of every phase some coils independently on structure clash is, lift one's head behind the suit and introduce outside the connection, such loop construction can solve the coil situation of cracking easily, improves the fail safe and the reliability of operation; The utility model is not fastenedly connected after directly not placing elastic rubber fitting between iron core, folder and the base, but increases pressure frame between iron core and elastic rubber fitting, and such structure can better reduce vibrations, and reduces noise, and reliability is better.
