Description
Technical field
The utility model is related to D.C. contactor protection device field, specially a kind of arc-control device of D.C. contactor.
Background technology
Contactor species is various, and electric arc can be all produced during the contactless contactor of contact-carrying, causes electromagnetism to do to surrounding environment
Disturb, calcination and damage are caused to contacts of contactor, have a strong impact on the electrical endurance of contactor.The high power DC machine of many occasions
Tool contactor electrical endurance not and its mechanical life 1 percent, therefore D.C. contactor generally require use various arc extinguishing skills
Art.
A kind of arc-control device of the prior art, is typically directly parallel in contactor two ends, when contactor is closed, can disappear
A certain amount of electric energy in major loop is consumed, unnecessary waste is caused.
Utility model content
The utility model purpose is to provide a kind of arc-control device of D.C. contactor.Avoid D.C. contactor closure connection
During major loop, the arc-control device of D.C. contactor consumes the electric energy of major loop.
In order to achieve the above object, the technical solution of the utility model has：
A kind of arc-control device of D.C. contactor, including encapsulating electric capacity and resistance, the encapsulating electric capacity are in series with a resistor；Also
Including diode, the diode and encapsulating electric capacity and resistant series, then it is overall in parallel with D.C. contactor；The positive pole of diode
D.C. contactor negative pole is connected by encapsulating electric capacity and resistance, the negative pole of diode connects the positive pole of D.C. contactor.
Further, in addition to an outer box, the outer box inner hollow and a side opening, the encapsulating being connected in series
Electric capacity, resistance and diode are encapsulated in outer box by insulating materials.The arc-control device is encapsulated in outer box by insulating materials,
The outer box and insulating materials can effectively prevent arc-control device not by external environment influence.
Further, the insulating materials is epoxy resin.Epoxy resin has good insulating properties, can coat completely
On arc-control device；Epoxy resin also has good resistance to acids and bases and resistant to elevated temperatures performance, and arc-control device is encapsulated in into outer box
In, arc-control device can be protected not influenceed by external environment.
Further, the lead that the encapsulating electric capacity, resistance and diode stretch out curves inwardly.Installation can be saved
Space, reduces the volume of outer box.
Further, the encapsulating electric capacity, resistance and diode are arranged side by side, and pass through copper strips anchor leg string
Connection.It is directly connected to by copper strips, can be reduced cost of labor；After copper strips connection, connection selects bent portion under high frequency occasion
A miniature inductance is can function as, high-frequency harmonic part can be filtered.
A kind of arc-control device of D.C. contactor of the present utility model, by a diode of being connected in arc-control device,
Arc-control device is connected in parallel on D.C. contactor again, the function of diode unilateral conduction is utilized so that contactor connects major loop
When, arc-control device is off, and will not consume the electric energy on major loop；When contactor disconnects major loop, arc-control device
With contactor one blow-out circuit of formation, protection contactor will not produce spark.Electric capacity is using encapsulating electric capacity so that arc-control device
In process of manufacture will not because lead touches capacitive surface and occurs short circuit, can effectively improve assembling speed there is provided
The yields of product, then entirely through epoxy encapsulation in outer box, protection and fixed arc-control device.

Hold 1 to connect with resistance 2；Also include diode 3, the diode 3 is connected with encapsulating electric capacity 1 and resistance 2, then entirety connects with direct current
Tentaculum is in parallel；The positive pole of diode 3 connects D.C. contactor negative pole by encapsulating electric capacity 1 and resistance 2, and the negative pole of diode 3 connects
Connect the positive pole of D.C. contactor.
Further, as shown in figure 3, also include an outer box 5, the inner hollow of outer box 5 and a side opening, it is described
Encapsulating electric capacity 1, resistance 2 and the diode 3 being connected in series are encapsulated in outer box 5 by insulating materials.
Further, the insulating materials is epoxy resin.Epoxy resin has good insulating properties, can wrap completely
Overlay on arc-control device；Epoxy resin also has good resistance to acids and bases and resistant to elevated temperatures performance, by arc-control device encapsulation outside
In box 5, arc-control device can be protected not influenceed by external environment.
Further, as shown in Fig. 2 the encapsulating electric capacity 1, resistance 2 and the lead 6 of the stretching of diode 3 are inwardly curved
It is bent.Installing space can be saved, the volume of outer box 5 is reduced.
Further, the encapsulating electric capacity 1, resistance 2 and diode 3 are arranged side by side, and pass through the anchor leg of copper strips 4
6 series connection.
Further, as shown in figure 3, arc-control device is encapsulated in outer box 5, two power lines 7 and interrupter cartridge are passed through
Connection, therefore package casing are put, can be in parallel with D.C. contactor.
The announcement and teaching of book according to the above description, the utility model those skilled in the art can also be to above-mentioned reality
The mode of applying is changed and changed.Therefore, the utility model is not limited to embodiment disclosed and described above, right
