Description
Technical Field
[0001] The utility model relates to the technical field of current limiting reactors, in particular to a multi-stage adjustable motor reactor. Background Art
[0002] A reactor connected in series in the power system to limit the fault current of the system. The current limiting reactor is an inductive element used to limit the closing inrush current, high harmonics, short-circuit fault current, etc. in the system. The reactor is made of copper or aluminum coils. The cooling methods include oil immersion and dry self-cooling. The structure of the support includes cement column type and clamping type. When a short circuit occurs in the power system, a large short-circuit current will be generated. If it is not restricted, it is very difficult to maintain the dynamic stability and thermal stability of electrical equipment. Therefore, in order to meet the requirements of the interrupting capacity of certain circuit breakers, reactors are often connected in series at the outgoing circuit breaker to increase the short-circuit impedance and limit the short-circuit current. Due to the use of the reactor, when a short circuit occurs, the voltage drop on the reactor is large, so it also plays a role in maintaining the bus voltage level, making the voltage fluctuation on the bus smaller, ensuring the stability of the operation of user electrical equipment on the non-fault line. The traditional motor current limiting reactor, the insulating film set on the outer wall of the internal winding coil is easily worn and broken after long-term use, which will cause the risk of leakage and further cause hidden dangers to the personal safety of the operator.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] See also Figure 1-6 , the utility model provides an embodiment: a multi-speed adjustable motor reactor, comprising two sets of bases 1;
[0024] Two sets of electrical connection sheets 2 are fixedly installed on opposite sides of the two sets of bases 1, and two sets of winding coils 3 are fixedly installed between the four sets of electrical connection sheets 2. The two sets of winding coils 3 are symmetrically arranged. Protection components are arranged between the four sets of electrical connection sheets 2 and on the two sets of winding coils 3. A limiting component is arranged at the connection between the protection component and the four sets of electrical connection sheets 2. The device installs the protection component between the four sets of electrical connection sheets 2, and protects the two sets of winding coils 3 by the protection component, and then fixes the protection component by the limiting component, so as to achieve the protection of the two sets of winding coils 3;
[0025] Furthermore, the protection component includes four groups of protective shells 4, which are movably sleeved on the front and rear sides of the two groups of winding coils 3. Two groups of sliders 5 are fixedly installed at the upper and lower ends of the four groups of protective shells 4. Two groups of slide grooves 6 are opened in the opposite sides of the four groups of electrical connecting pieces 2. Eight groups of sliders 5 are movably inserted in the eight groups of slide grooves 6. This device movably inserts the four groups of protective shells 4 into the eight groups of slide grooves 6 through the eight groups of sliders 5, so that the four groups of protective shells 4 are sleeved on the front and rear sides of the two groups of winding coils 3, so as to protect the outer walls of the two groups of winding coils 3.
[0026] Furthermore, the four groups of protective shells 4 are all U-shaped, and the inner walls of the four groups of protective shells 4 are larger than the outer walls of the two groups of winding coils 3. This structure, based on the shape of the four groups of protective shells 4, enables the two groups of winding coils 3 to be sealed and protected when the four groups of protective shells 4 are symmetrically connected front and back.
[0027] Furthermore, the inner walls of the four groups of protective shells 4 are glued with insulating pads 7, and the four groups of insulating pads 7 are in contact with the outer walls of the two groups of winding coils 3. When the four groups of protective shells 4 protect the two groups of winding coils 3, the insulating pads 7 on the inner walls of the four groups of protective shells 4 are in contact with the outer walls of the winding coils 3, thereby preventing the winding coils 3 from being funneled onto the protective shells 4.
[0028] Furthermore, the limiting assembly includes eight groups of fixed blocks 8, which are fixedly installed on four groups of electrical connection plates 2. The eight groups of fixed blocks 8 are fitted with the joints of the four groups of protective shells 4. Two groups of movable grooves 9 are opened in the eight groups of fixed blocks 8, and limiting blocks 10 are installed in the movable grooves 9. Limiting grooves 11 are opened at the upper and lower ends of the four groups of protective shells 4. The limiting blocks 10 are inserted in the limiting grooves 11. Springs 12 are installed in the movable grooves 9. Pull rods 13 are installed in the fixed blocks 8. The pull rods 13 are fixedly connected to the two groups of limiting blocks 10 in the two groups of movable grooves 9 on the fixed blocks 8. After the protective shell 4 is set to protect the two groups of winding coils 3, the two groups of limiting blocks 10 in the eight groups of fixed blocks 8 are inserted into the limiting grooves 11 on the four groups of protective shells 4, so as to limit and fix the four groups of protective shells 4, and the limiting blocks 10 can be pulled out of the limiting grooves 11 by pulling the pull rods 13, which is convenient for quick replacement and installation of the protective shell 4.
[0029] Furthermore, the ends of the limit blocks 10 in the two groups of movable grooves 9 on the fixed block 8 that are inserted in the limit grooves 11 are all inclined, and the inclined surfaces of the ends of the limit blocks 10 in the two groups of movable grooves 9 on the fixed block 8 that are inserted in the limit grooves 11 are symmetrically arranged front and back. This structure is based on the direction of the inclined surfaces of the two groups of limit blocks 10 in the fixed block 8, so that when the four groups of protective shells 4 are sleeved on the two groups of winding coils 3, it is convenient for the protective shells 4 to squeeze the limit blocks 10 open.
[0030] Furthermore, the spacing between the opposite sides of the fixing blocks 8 on the left and right sides of the four groups of electrical connection sheets 2 is the same as the width of the left and right sides of the four groups of protective shells 4, and the opposite sides of the fixing blocks 8 on the left and right sides of the four groups of electrical connection sheets 2 are fitted with the left and right sides of the four groups of protective shells 4. This structure is based on the spacing between the fixing blocks 8 on the left and right sides of the electrical connection sheets 2 and the width of the left and right sides of the protective shell 4, so that the left and right sides of the protective shell 4 can be tightly fitted with the opposite sides of the fixing blocks 8 at the left and right ends of the electrical connection sheets 2.
[0031] Furthermore, the inner wall of the slide groove 6 and the slider 5 are both T-shaped, and the inner wall of the slide groove 6 is adapted to the slider 5. This structure is adapted to the inner wall of the slide groove 6 and the slider 5 to prevent the slider 5 from being pulled up and down from the slide groove 6 after being inserted into the slide groove 6.
[0032] Working principle: When protecting the winding coil 3, Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, four groups of protective shells 4 are movably inserted into two groups of slide grooves 6 on two groups of electrical connecting sheets 2 through two groups of sliders 5 at the upper and lower ends, and after the sliders 5 are inserted into the slide grooves 6, the four groups of protective shells 4 are butted and fitted together, and the protective shells 4 squeeze the limit blocks 10 when sliding, and the limit blocks 10 slide into the movable grooves 9 under the squeezing, and after the four groups of protective shells 4 are butted and fitted together, the limit blocks 10 in the movable grooves 9 pop out under the action of the restoring elastic force of the spring 12, and after the limit blocks 10 pop out, they are inserted into the limit grooves 11 at the upper ends of the protective shells 4, so that the protective shells 4 can be limited and fixed. The above is the entire working principle of the utility model.
