Abstract
The utility model relates to a self-saturated reactor comprising iron core cakes, a working winding, a controlling winding, a excursion winding, a box body, the structure of which is characterized in that the two ends of the working winding can't turn and is electrically connected with two external wire terminals which are fixed on box walls and correspond to the two ends of the working winding. Every iron core cake is assembled along the axes horizontal direction to forms a horizontal type iron core. The utility model has the advantages of no local overheat on the end face of iron core cake on the two ends, low loss, low vibration, low noise, high stability, high reliability, small volume, and low cost. The utility model is especially applicable to the self-saturated reactor on the side of a rectifier transformer valve.
Description
Affiliated technical field
The utility model belongs to the variable inductor that variable magnetic biasing is arranged, and is specially adapted to the autotransducer of rectifier transformer valve side.
Background technology
At present, the autotransducer that is connected on rectifier transformer valve side is that the iron core that is made of cake unshakable in one's determination, the work winding that passes cake unshakable in one's determination, DC control winding, direct current offset winding etc. constitute.Its objective is: by adjusting the VD after DC control winding current or direct current offset winding current are regulated rectification.Its weak point is: 1, because iron core is to be made of the vertical closed assembly of cake unshakable in one's determination, after need turning round in the two ends of the work winding that runs through cake unshakable in one's determination and be made of copper bar again be fixed on tank wall on outlet terminal be connected, turn round the copper bar that connects respectively apart from two cake end faces unshakable in one's determination are nearer up and down, the high-intensity magnetic field that flows through the big electric current generation of copper bar produces local overheating at cake end face up and down unshakable in one's determination, loss increases, even burns iron core; Simultaneously, because the effect of this high-intensity magnetic field makes the electrical steel sheet produce vibration, increased the noise of product; 2, because iron core is to be made of the vertical closed assembly of cake unshakable in one's determination, so device body center of gravity is higher, less stable; 3, because iron core is a vertical structure, so the device body is difficult for fixingly, in servicely will produce bigger vibration and noise, poor reliability.
Summary of the invention
For overcoming the weak point of existing autotransducer, the utility model intends providing the no local overheating of a kind of iron core, the device body is stablized, loss is little, vibration is little, noise is little, reliability is high, cost is low autotransducer.
The technical solution of the utility model is realized by following technical measures: it comprises cake unshakable in one's determination, work winding, control winding, skew winding, casing etc., its special character is: do not turn round in the two ends of work winding, and be fixed on the box body wall and be electrically connected respectively with the corresponding outlet terminal in work winding two ends; Each cake unshakable in one's determination constitutes horizontal iron core along its axle center horizontal direction assembling.
The beneficial effects of the utility model:
1, do not turn round owing to work winding of the present utility model two ends, and be fixed on the box body wall and be electrically connected respectively with the corresponding outlet terminal in work winding two ends, cake end face local overheating unshakable in one's determination and the big deficiency of loss that the winding two ends copper bar of having avoided working in the prior art causes because of turning round, therefore, the utility model two cake end faces unshakable in one's determination do not have local overheating, and loss is low, vibrate simultaneously little, noise is low;
2, because iron core of the present utility model is a horizontal type structure, the device body center of gravity that is made of unshakable in one's determination, work winding, control winding, skew winding etc. is low, so the device body is easy to fixing then good stability, vibration is little, noise is low, reliability is high;
3, because the horizontal placement of device body, the copper bar at work winding two ends does not turn round, and has therefore saved material, small product size is little, cost is low.

Fig. 1 is the prior art structural representation;
Fig. 2 is the utility model example structure schematic diagram.
Among the figure: 1, binding post, 2, lug plate, 3, the work winding, 4, cake unshakable in one's determination, 5, draw screw rod, 6, the control winding, 7, clamping plate, 8, skew winding 9, backing plate 10, support, 11, casing, 12, insulating pad.
Specific embodiment
With reference to Fig. 2.The work winding (3) that is made of copper bar runs through each cake unshakable in one's determination (4) that constitutes iron core.Do not turn round through lug plate (2) and be fixed on casing (11) wall and with work winding (3) corresponding two outlet terminals in two ends (1) and be electrically connected respectively in the two ends of work winding.Constitute horizontal iron core by each cake unshakable in one's determination (4) along its axle center horizontal direction assembling.Be lined with insulating pad (12) between each cake unshakable in one's determination (4).By the clamping plate (7) at two ends unshakable in one's determination, draw screw rod (5) that each cake unshakable in one's determination (4) is clamped.Core portion in work winding (3) both sides is wound with control winding (6), skew winding (8) respectively.Be equipped with backing plate (9) between the bottom by unshakable in one's determination, work winding (3), control winding (6), the device body bottom that is offset winding formations such as (8) and casing (11), and fix by the lower end of support (10), clamping plate (7) and the bottom of casing (11).
Claims (2)
1, a kind of autotransducer, comprise cake unshakable in one's determination, work winding, control winding, skew winding, casing etc., it is characterized in that: do not turn round in the two ends of work winding, and be fixed on box body wall on and be electrically connected respectively with corresponding two outlet terminals in work winding two ends.
2, a kind of autotransducer according to claim 1 is characterized in that: each cake unshakable in one's determination constitutes horizontal iron core along its axle center horizontal direction assembling.
