Abstract
The invention discloses a combined insulation connection structure of an electromagnet and a vacuum arc-extinguishing chamber. The connection structure disclosed by the invention is an isolation combined flange; the isolation combined flange is formed by an electromagnet connection flange and a vacuum arc-extinguishing chamber connection flange; the two flanges including the electromagnet connection flange and the vacuum arc-extinguishing chamber connection flange are embedded together; an injection molding insulating body is filled into an embedding crack; the vacuum arc-extinguishing chamber connection flange is provided with a screw rod; and the electromagnet connection flange is provided with a central shaft containing a screw hole. According to the combined insulation connection structure disclosed by the invention, electric isolation is realized on a connection part of the electromagnet and the vacuum arc-extinguishing chamber, so that an electromagnet coil is effectively protected, and the possibility of damaging the electromagnet is reduced. Furthermore, the crosstalk to a control circuit by a main circuit in the electromagnet and a vacuum pipe assembly is greatly eliminated, and the safety of mineral switching equipment is improved.
Description
Technical field
The present invention relates to the syndeton that insulate, more particularly, relate in a kind of combined switch for mining (containing the frequency conversion switch), with the syndeton of electromagnet and vacuum interrupter realization electrical isolation.
Background technology
In mine explosion-suppression and intrinsic safety holotype unit switch (hereinafter to be referred as switch) lining, the closure of vacuum interrupter moving contact, disconnection is driven by electromagnet, it is again to be controlled by its coil that includes that the adhesive of electromagnet discharges, present most structures are that electromagnet directly is connected with vacuum interrupter, are the equipotentiality body between the two.When electromagnetic actuation, vacuum interrupter moving contact closure, this moment, electromagnet also was with forceful electric power, although the coil in the electromagnet has been taked some insulation quarantine measures, but the situation that coil punctures happens occasionally, thereby has caused the damage of contactor in the switch or isolating switch, influences the use of switch.
On the other hand, in switch, what electromagnet connected is control circuit, what vacuum interrupter connected is main circuit, if electromagnet directly is connected with vacuum interrupter, main circuit can produce control circuit and disturb, influence the work of control circuit, this phenomenon is particularly evident in the frequency conversion switch.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the deficiencies in the prior art, and the combined insulation syndeton of a kind of electromagnet and vacuum interrupter is provided.
The combined insulation syndeton of electromagnet of the present invention and vacuum interrupter, be achieved by following technical proposals, described syndeton is for isolating Ifold flange, described isolation Ifold flange is made up of electromagnet adpting flange and vacuum interrupter adpting flange, two flanges of described electromagnet adpting flange and vacuum interrupter adpting flange nest together, the injection moulding insulator is filled in described nested slit, described vacuum interrupter adpting flange arranges screw rod, and the setting of described electromagnet adpting flange contains the central shaft of screw.
Compared with prior art, the invention has the beneficial effects as follows:
When the present invention structurally realizes electromagnet to be connected with vacuum interrupter, on electric, to realize isolating between the two.The present invention realizes electrical isolation at electromagnet and vacuum interrupter junction, has not only protected electromagnet coil effectively, has reduced the probability that electromagnet damages.And eliminated greatly in electromagnet and the vacuum pipe assembly, main circuit is crosstalked to control circuit, has improved the stability of mining switchgear.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.Should be appreciated that specific embodiment described herein only in order to explaining the present invention, and be not used in restriction the present invention.
As shown in Figure 1, described syndeton is for isolating Ifold flange, described isolation Ifold flange is made up of electromagnet adpting flange 1 and vacuum interrupter adpting flange 2, two flanges of described electromagnet adpting flange and vacuum interrupter adpting flange nest together, injection moulding insulator 5 is filled in described nested slit, described vacuum interrupter adpting flange arranges screw rod 3, and the setting of described electromagnet adpting flange contains the central shaft 4 of screw.
Syndeton of the present invention mainly realizes that by isolation flange isolation flange one end is connected with electromagnet, and the other end is connected with vacuum interrupter.Isolation flange is a kind of insulation union piece, is made up of electromagnet adpting flange and two steel flanges of vacuum interrupter adpting flange.Earlier two flanges are nested together, then at junction injection moulding insulating material, with this two flanges are linked into an integrated entity, simultaneously the not conducting of two ends of two flanges.Realized that by isolation flange electromagnet is connected with the insulation of vacuum interrupter.
It is little that the present invention has a structure space, is convenient to assembling and maintenance, and the reliability advantages of higher is applicable in the mining equipments such as combined switch for mining and mining frequency conversion switch.
The above only is preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
