Abstract
The invention relates to a switching device with a housing bottom (1), wherein a stationary iron core (2) and a coil (4) of an electromagnet serving as switch actuator are embedded in a casting compound (9) serving as housing. Optionally, a flow sensor (5) and control electronics (6) may be potted with the casting compound. The housing bottom (1) can be produced in a cost-effective manner using a mold to position the components.
Description
The present invention relates to a kind of switchgear, it has an electromagnet as switch driver.This electromagnet comprises a secured core and a magnet exciting coil, and the two all is arranged in the housing bottom spare as structural elements.
The switchgear of the above-mentioned type is disclosed by German patent application DE 19716380A1 already, and wherein, iron core is installed on the base plate in the housing bottom spare inner chamber.
Known by Germany Patent document DE 8207239 U1, with a kind of appropriate plastic material an annular magnet transformer teeming is sealed, so that make annular magnet transformer, switch, terminal board and be connected the full unit that lead constitutes a compactness.Germany Patent document DE 29519091 U1 have described a kind of be used to pour into a mould installation electric structural elements, the especially casing device of a transformer.This electricity structural elements is connected with a protection component that prevents overcurrent.A PTC-element is cast in the casting material with structural elements, for example is cast in the epoxy resin.Another piece Germany Patent document also discloses a kind of structural elements, and the winding of one of them transformer and PTC-resistance thereof all are embedded in the mould material.
The objective of the invention is to improve the switchgear of the above-mentioned type, make housing bottom spare can create by iron core, coil at an easy rate, may also have magnetic flux transducer and control the structural elements that electronic component is formed.
The object of the present invention is achieved like this promptly, is embedded in iron core and coil in the mould material, constitutes housing bottom spare by them.
Outpour the sleeve that is used for fixing the housing upper-part in order between a upper-part of housing bottom spare and switchgear, to set up a kind of simple connection, more advantageously in housing bottom spare, to water.
Favourable improvement structure of the present invention is, in a groove of iron core a magnetic flux transducer is set, and it is electrically connected with a control electronic component, and wherein this magnetic flux transducer and control electronic component are embedded in the mould material.
The present invention also aims to provide a kind of method of producing switchgear in addition, this switchgear has an electromagnet as switch driver, and it comprises a secured core and a magnet exciting coil, and the two all is arranged in the housing bottom spare.
This purpose realizes like this, that is, make iron core and magnetic coil be fixed on one and water in the mold, and this mold is poured into a mould with mould material subsequently.
According to favourable improvement design of the present invention, in mold, also in addition a magnetic flux transducer and a control electronic component that is electrically connected with it that is positioned at the iron core groove is poured into a mould.
More advantageously, described pouring piece is configured to housing bottom spare, and described mold has corresponding in-profile.
Below by an accompanying drawing to one embodiment of the invention, described in detail according to the structure and the manufacture method thereof of switchgear of the present invention.
The housing bottom spare of a switchgear shown in the accompanying drawing 1, it has 4, one magnetic flux transducers 5 of coil and a control electronic unit 6 on an E sections core 2 and the limit leg 3 that sets within it basically.These parts all are embedded in the mould material 7 that constitutes housing bottom spare 1 shell simultaneously.Magnetic flux transducer 5 is arranged in the groove 8 of iron core 2 and is used to measure magnetic flux in the iron core 2.This magnetic flux transducer is electrically connected with control electronic component 6 in being arranged on mould material 7 equally.Housing bottom spare has the attachment strap 9 of side direction projection, has fixing hole 10 on this attachment strap, so that switchgear can pass through housing bottom spare 2 bolt.At the upside of housing bottom spare, in that two outer side edges legs of iron core 2 are other embedding respectively a threaded sleeve is arranged, so that the upper-part of floatless switch equipment.
Housing bottom spare 1 can come to make at an easy rate as follows: with iron core 2 and prefabricated coil 4, and also have control electronic component 6 and magnetic flux transducer 5 and be fixed on one and water in the mold, and pour into a mould with mould material 7 subsequently, all parts are linked up mutually.This can be simultaneously with sleeve 11 and may the essential guide member that is used for the switchgear upper-part be fixed on this equally and water in the mold and pour into a single-casting together.
Above-mentioned switchgear can be made at an easy rate, and its structure is also very firm.It can avoid the influence of aggressivity chemical substance, can obtain corrosion resistance.Has the good characteristic that derives of heat simultaneously with iron core 2 and coil 4.Also can obtain the favorable mechanical damping performance by correspondingly regulating mould material.In a magnetic flux transducer 5 and one control electronic component 6 is installed in, make magnetic flux detect and regulate control to combine.This switchgear of producing with permanent protective property energy also has many other advantages.
