Abstract
The invention discloses a permanent magnetic mechanism with a closing holding coil, which comprises a closing and opening coil (1), a closing holding coil (2), permanent magnets (3) and a shell (4). When the permanent magnetic mechanism with the closing holding coil needs closing or opening, current only needs to be provided between a tap A1 and a tap A3 of the closing and opening coil (1), a magnetic force is generated, and closing and opening operation of the permanent magnetic mechanism is promoted; after closing of the permanent magnetic mechanism is finished, current is provided between a tap A1 and a tap A2 of the closing holding coil (2), the generated magnetic force and the magnetic force generated by the permanent magnets together enable the permanent magnetic mechanism to maintain in the closing state; and thus, on the premise that the permanent magnetic mechanism with the closing holding coil enables the closing holding force to be unchanged, the number of the permanent magnets (3) is reduced, and the size of the shell (4) of the permanent magnetic mechanism is greatly reduced.
Description
Technical field
The present invention relates to a kind of indoor high-voltage circuit breaker, especially relevant with indoor permanent magnetic mechanism primary cut-out.
Background technology
The permanent magnet mechanism splitting or integrating lock operation of existing indoor high-voltage circuit breaker adopts the fault offset of splitting or integrating brake cable circle respectively, closes a floodgate and keeps adopting permanent magnet.Such permanent magnet mechanism volume can be larger, is unfavorable for being arranged on miniature circuit breaker.
Summary of the invention
The present invention mainly provide a kind of when closing retention force and combined floodgate merit constant, the permanent magnet mechanism that volume reduces greatly
Technical scheme of the present invention is: a kind of permanent magnet mechanism with combined floodgate hold-in winding, (forward current is and brake cable circle to comprise splitting or integrating brake cable circle, reverse current is switching winding, wherein tap A1 and tap A3 is splitting or integrating brake cable circle), (tap A1 and tap A2 is combined floodgate hold-in winding to combined floodgate hold-in winding, and combined floodgate hold-in winding is a part for splitting or integrating brake cable circle), permanent magnet and housing, it is characterized in that, keep by permanent magnet and the acting in conjunction of combined floodgate hold-in winding at combined floodgate.
The permanent magnet mechanism of indoor high-voltage circuit breaker band combined floodgate hold-in winding provided by the invention, when the indoor high-voltage circuit breaker of the permanent magnet mechanism being with combined floodgate hold-in winding is in "on" position, closing retention force is made up of two parts, respectively: (wherein combined floodgate hold-in winding is maintained by certain electric current for the magnetic force that permanent magnet produces and the magnetic force that combined floodgate hold-in winding produces, combined floodgate hold-in winding is certain a bit additional tap in the middle of closing coil, and namely combined floodgate hold-in winding is a part for closing coil).Under the prerequisite remained unchanged at switching force like this, permanent magnet quantity reduces, thus the volume of permanent magnet mechanism housing reduces, and theory calculate reduces about 1/3rd.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing permanent magnet mechanism;
Fig. 2 is the structural representation of the permanent magnet mechanism embodiment of band combined floodgate hold-in winding of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
In figure: 1, splitting or integrating brake cable circle 2, combined floodgate hold-in winding 3, permanent magnet 4, housing
As shown in Figure 2, the permanent magnet mechanism of band combined floodgate hold-in winding of the present invention, comprise splitting or integrating brake cable circle 1, combined floodgate hold-in winding 2, it is characterized in that, combined floodgate hold-in winding 2 is a part for splitting or integrating brake cable circle 1, i.e. have more A2 tap between two tap A1 and A3 of splitting or integrating brake cable circle 1, the loop formed between A1 and A2 is wherein exactly combined floodgate hold-in winding 2, its number of turn is less than splitting or integrating brake cable circle 1, and does not need to increase coil separately.
When being with the permanent magnet mechanism of combined floodgate hold-in winding to need combined floodgate or separating brake, only between splitting or integrating brake cable circle 1 (tap A1 and tap A3), passing into electric current, producing magnetic force, impel permanent magnet mechanism splitting or integrating lock to operate; After permanent magnet mechanism has closed a floodgate, combined floodgate hold-in winding 2 (tap A1 and tap A2)) between pass into electric current, the magnetic force that the magnetic force produced and permanent magnet produce makes permanent magnet mechanism remain on "on" position jointly, under the prerequisite constant in closing retention force of the permanent magnet mechanism of this belt transect combined floodgate hold-in winding, the quantity of permanent magnet 3 reduces, thus the volume of permanent magnet mechanism housing 4 reduces greatly.
Claims (2)
1. the permanent magnet mechanism with combined floodgate hold-in winding, comprises splitting or integrating brake cable circle (1), combined floodgate hold-in winding (2), permanent magnet (3) and housing (4); It is characterized in that: extract the part of combined floodgate hold-in winding (2) as splitting or integrating brake cable circle (1) out in the inside of splitting or integrating brake cable circle (1).
2. a kind of permanent magnet mechanism with combined floodgate hold-in winding according to claim 1, it is characterized in that, A2 tap is had more between two tap A1 and A3 of splitting or integrating brake cable circle 1, the loop formed between A1 and A2 is wherein as combined floodgate hold-in winding 2, its number of turn is less than splitting or integrating brake cable circle 1, and does not increase coil separately.
