Definitions
- Switchgear with a lower housing section as a structural unit and associated manufacturing process
- the invention relates to a switching device with a solenoid serving as a switching drive, which comprises a fixed iron core and an excitation coil, both of which are arranged in a lower housing part as a structural unit.
- a generic switching device is disclosed in DE 197 16 380 AI.
- the iron core is housed on the floor in the interior of the lower part of the housing.
- DE 82 07 239 UI it is known to cast a ring transformer with a covering made of a suitable plastic compound in order to achieve a compact structure of an entire unit, consisting of a ring transformer, switch, terminal box and connecting lines.
- DE 295 19 091 UI describes a housing arrangement for encapsulating an electronic component, in particular a transformer, which is connected to a protective element against overcurrent.
- a PTC element is placed together with the structural unit in a casting compound, e.g. made of epoxy resin, potted.
- DE 26 48 546 C2 also discloses a structural unit in which the windings of a transformer and its PTC resistor are embedded in a casting compound.
- the invention has for its object to improve a switching device of the above type in such a way that the lower housing part as a structural unit consisting of iron core, coil and possibly.
- Flow sensor and control electronics is inexpensive to manufacture.
- the object is achieved in that the iron core and the
- Coil are embedded in potting compound, through which the lower housing part is formed.
- potting compound through which the lower housing part is formed.
- a flow sensor is arranged in a recess in the iron core and is electrically connected to control electronics, the flow sensor and the control electronics being embedded in the casting compound.
- the invention is based on the object of specifying a method for producing a switching device which has an electromagnet which serves as a switching drive and which comprises a fixed iron core and an excitation coil, both of which are arranged in a lower housing part.
- This object is achieved in that the iron core and the magnetic coil are positioned in a mold and the mold is then cast with a casting compound.
- the shape of a flow sensor lying in a recess in the iron core and a control electronics electrically connected to it are additionally cast.
- the potting is advantageously designed as a lower housing part, and the shape has corresponding inner contours.
- a lower housing part 1 of a switching device which essentially has an E-shaped iron core 2 with a coil 4 arranged over its inner leg 3, has a flow sensor 5 and control electronics 6.
- the components mentioned are embedded in a casting compound 7, which also forms the housing of the lower housing part 1.
- the flow sensor 5 is arranged in a recess 8 of the iron core 2 and is used to measure the magnetic flux in the iron core 2. It is electrically connected to the control electronics 6, which is likewise arranged in the sealing compound 7.
- the lower housing part has laterally projecting webs 9, which are provided with fastening bores 10, so that the switching device can be screwed onto the lower housing part 2.
- a socket 11 with a thread for fastening an upper part of the switching device is embedded.
- the lower housing part 1 can be manufactured inexpensively according to the following method.
- the iron core 2 and the prefabricated coil 4 as well as possibly the control electronics 6 and the flow sensor 5 are positioned in a mold and then cast by the casting compound 7 in such a way that all of them
- the sockets 11 and any necessary guides for an upper part of the switching device can also be positioned in the mold and cast in a joint casting.
- the switching device described above can be manufactured cheaply and has a robust construction. It resists the effects of aggressive chemicals and is protected against corrosion. This results in good heat conduction from the iron core 2 and the coil 4 and good damping of mechanical vibrations by appropriate adjustment of the potting compound. With the likewise integrated flow measurement and control by installing a flow sensor 5 and control electronics 6, there are further advantages of the switching device which can be produced with a high degree of protection.
