Abstract
The utility model discloses an integrated insulation connection structure of an electromagnet and a vacuum arc-extinguishing chamber. The structure of the utility model comprises the electromagnet and the vacuum arc-extinguishing chamber. The electromagnet and the vacuum arc-extinguishing chamber are connected through an insulation screw cover. A periphery of a main shaft of the insulation screw cover is provided with an external screw thread. The main shaft of the insulation screw cover is provided with a screw hole. According to the structure of the utility model, electrical isolation on a joint of the electromagnet and the vacuum arc-extinguishing chamber is realized; an electromagnet coil is effectively protected and a damage probability of the electromagnet is reduced; in the electromagnet and a vacuum pipe assembly, crosstalk of a main circuit to a control circuit is greatly eliminated; stability of mining switch equipment is increased.
Description
Technical field
The utility model relates to insulation connection structure, more particularly, relates in a kind of combined switch for mining (containing the frequency conversion switch), electromagnet and vacuum interrupter is realized the syndeton of electrical isolation.
Background technology
Inner at mine explosion-suppression and intrinsic safety holotype unit switch (hereinafter to be referred as switch), 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 both.When electromagnetic actuation, the vacuum interrupter moving contact is closed, and this moment, electromagnet also was with forceful electric power, although the coil in 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, affects 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, affect the work of control circuit, this phenomenon is particularly evident in the frequency conversion switch.
The utility model content
Technical problem to be solved in the utility model is, overcomes the deficiencies in the prior art, and the one insulation connection structure of a kind of electromagnet and vacuum interrupter is provided.
The one insulation connection structure of the utility model electromagnet and vacuum interrupter, be achieved by following technical proposals, comprise electromagnet and vacuum interrupter, it is characterized in that, described electromagnet is connected by the insulation helical casing with vacuum interrupter, the main shaft periphery of insulation helical casing arranges external screw thread, and the main shaft of insulation helical casing arranges screw.
Compared with prior art, the beneficial effects of the utility model are:
When the utility model is structurally realized electromagnet to be connected with vacuum interrupter, to realize isolation between the two on electric.The utility model is realized electrical isolation at electromagnet and vacuum interrupter junction, has not only effectively protected electromagnet coil, has reduced the probability that electromagnet damages.And greatly eliminated in electromagnet and vacuum pipe assembly, main circuit is crosstalked to control circuit, has improved the stability of Mine Switch equipment.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in and limit this utility model.
As shown in Figure 1, described electromagnet is connected by insulation helical casing 1 with vacuum interrupter, and the main shaft periphery of insulation helical casing arranges external screw thread 2, and the main shaft of insulation helical casing arranges screw 3.
During assembling, the main shaft of the swivel nut that first will insulate screws in the screw of the first end of vacuum interrupter movable contact, then the screw shaft in electromagnet is screwed in the screw of insulation swivel nut main shaft, like this, has realized that by the insulation swivel nut electromagnet is connected with the insulation of vacuum interrupter.
The above is only preferred implementation of the present utility model; should be noted that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
