Description
Technical field
The invention belongs to relay technical fields, and in particular to a kind of grid arc-control device and its relay, in particular one
Kind high-voltage motor formula Worm and Worm Gear Driving DC relay and its grid arc-control device for swinging door cover type.
Background technology
Relay is a kind of control element, is a kind of contactor and the device with protective nature, application are very extensive.?
New-energy automobile field, as the relay of core component, major function is to control high voltage circuit with low-voltage remote to lead to
Disconnected switch (controlling unsafe 300~1000V of high voltage with 12~72V of safety low-voltage).It can be seen that relay is actually
One kind " automatic switch " of control high current running is gone with low current and forms safeguard protection machine with other components in circuit
The effects that system and conversion circuit.Electric motor type worm and gear and rack deceleration mechanism DC relay are and conventional electromagnetic relay
A kind of different new type of relay, cardinal principle are the micro motor for driving worm and gear and The gear deceleration by Small current control
Mechanism is by the quick-make of relay electrode contact or pulls open and achievees the purpose that circuit " switch ", and feature is that have that action is fast, body
The features such as product is small, arc extinguishing is safe (related to spacing is pulled open), Reliability of Microprocessor is high, long lifespan.
In high-voltage large current, any connecting and disconnecting of the circuit operation can all generate electric arc or spark, the electricity of the higher generation of voltage
Arc is longer, and electric current is bigger, and calorific value is bigger, and longer electric arc is possible to hit operating personnel or controller circuitry or high temperature is burnt out
Control circuit board is allowed to fail.The special switch applied in high-power high-current industry, system excessively complexity and huge, control
Energy consumption processed is huge, is only suitable for specific engineering；And develop meet miniaturization, high current, low consumption, safe arc extinguishing it is long-range
Switch relay is controlled, will be had broad application prospects in New Energy Industry.
It is many in the application scenario of the high-tension current relay arrived involved in new energy industry.Mainly to New Energy Industry
Electric power protection, automation, movement, prison are realized in middle automobile, solar energy, wind energy, charging pile, power storage system, industrial automation etc.
Control, measurement and communication etc.；Especially in new-energy automobile, battery charging and discharging circuit switching and protection are combined into anti-equipment event
Barrier or short circuit, the security mechanisms such as on fire, automatic detection and isolated fault circuit are prevented further expanding damage equipment range, be saved
Maintenance cost, proof and electric leakage-proof safety, and battery is effectively improved to the break-makes control such as air-conditioning, steering, brake, air pump, motor
System, is new-energy automobile core element.
Electric motor type relay is put forward when reaching bottleneck stage for its technology development of traditional electromagnetic type relay,
Meter industry is promoted and applies low pressure low current electric motor type relay at home, shown its structure, cost,
Various advantages such as energy consumption, performance.
For the requirement of new-energy automobile sector application, big voltage and the DC relay of high current, performance are needed
The key of feature is miniaturization, low-power consumption, safe arc extinguishing, anti-strong motion.Traditional relay is improved according to the requirement of load
And input power need to be improved, and its contact pressure is a constant numerical value, for arc extinguishing, needs individually designed contact part
Sealing room is flushed with hydrogen the auxiliary bodies such as gas, magnetic blow-out, volume, power consumption and cost is increased naturally, in particular with voltage, electric current
Load improve, structure must accordingly increase, and power consumption and cost also sharply increase the raising of and anti-shake performance, even more one
A bottleneck is difficult to meet the requirement that its relay does not change state in new-energy automobile cross-country ability.And use micro- direct current
Driving power of the motor as relay itself designs relay, profit by the deceleration mechanism of worm and wormwheel and gear composition
With the self-locking of worm and gear, contact pressure can be kept, it is impossible to change the state of contact under external force, together
When, in terms of meeting electrical load requirements, transmission mechanism do not have to increase with the increase of load how much, therefore in high-power big load
Relay on, more have the advantage of its cost and performance.
However, there is also its limitations for the method for reaching arc extinguishing by quickly pulling open one determining deviation of electrode contact, it is former
Because being influenced by mechanism space layout, the spacing that electrode contact can be opened is limited, it requires the relay of miniaturization
The voltage range that device can be born is also limited, and with the raising of extinguishing voltage, then need the required minimum detached of complete arc extinguishing
Spacing can be increasing (as when voltage reaches 10kV in the air, the spacing that normal arc extinguishing needs will reach 1m)；If so examining
Consider using traditional auxiliary extinction of arc measure, such as vacuumize, to be flushed with hydrogen gas, magnetic blow-out arc-suppressing method also very unreliable, to making work
Skill requires height, cost also high；Thus we original motor formula relay can will be between electrode by micro machine Worm Wheel System
On the basis of pulling open a determining deviation, the Promethean auxiliary extinction of arc method for adding door cover type arc extinguishing grid is reintroduced, to be applied to
On high-voltage motor formula relay construction device, the complete reliable arc extinguishing of high-current circuit had not only been realized, but also can continue to keep electric motor type
Relay miniaturization, low-power consumption, anti-strong motion protrusion effect.
