Description
Technical field
The present invention relates to a kind of electric switchgear, the electric switchgear more particularly to triggered with water pressure, belongs to electric physics
Learn technical field.
Background technology
Switch refers to that one can make open circuit, the electronic component for making current interruptions or making it flow to other circuits.Open
The principle of pass is the " closed " of contact（closed）Represent electronic contact conducting, it is allowed to which electric current flows through；" open circuit "（open）Represent
Electronic contact is not turned on forming open circuit, does not allow electric current to flow through.
It is divided into waved switch, band switch, playback switch, power switch, preselection switch, limit switch etc. according to purposes.
It is divided into microswitch, ship type switch, toggle switch, toggle switch etc. according to structure.
Simplest switch has two metals for being named as " contact ", electric current is formed loop, two contacts during two contacts
Current open when not contacting.It need to be considered during from contact metal to erosion-resisting degree, because meeting after most metals oxidation
The oxide of insulation is formed, makes contact can not normal work.From contact metal it is also contemplated that its electrical conductivity, hardness, machinery are strong
Degree, cost and whether the factor such as poisonous.Noncorroding metal is electroplated on contact sometimes.The contact surface of contact can be typically plated in,
To avoid influenceing its performance because of oxide.Sometimes contact surface can also use nonmetallic conductive material, such as conductive plastic.Switch
In in addition to contact, also have movable piece make contact turn on or be not turned on, switch can not be all to be divided into lever according to movable piece
Switch（Toggle switch）, key switch, ship type switch（Rocker switch）Deng, and movable piece can also be its alloytype
The mechanical linkage of formula.
Rated voltage：The voltage that the safe voltage that refer to switch is allowed in normal work is added in switch ends is more than
This value, sparking breakdown between two contacts can be caused.
Rated current：Allow the maximum safe current passed through, when more than this value, the contact of switch when referring to switch connection
It can be burnt because electric current is excessive.Insulaion resistance：Refer to the conductor part of switch and the resistance value of insulated part, insulating resistance value should be
More than 100M Ω.Contact resistance：Refer to switch in the on state, the resistance value between each pair contact is typically required in 0.1-
0.5 below Ω, this value are the smaller the better.It is pressure-resistant：Refer to the ceiling voltage switched to can bear between conductor and ground.Life-span：Refer to
In normal working conditions, operable number typically requires at 5000-35000 times or so switch.
Optoelectronic switch is the member in sensor extended familys, and it converts the strong and weak change of light between transmitting terminal and receiving terminal
It is the change of electric current to reach detection purpose.It is electrically isolated due to optoelectronic switch output loop and input circuit（I.e. electric edge
Absolutely）, so it can be applied in many occasions.
The New Generation Optical electric switch device that optoelectronic switch is manufactured using integrated circuit technique and SMT surface mounting technologies,
With delay, broadening, it is outer it is synchronous, anti-interfere, reliability is high, working region is stable and the intelligent functions such as self diagnosis.This
The novel optoelectronic switch of kind is a kind of using pulse modulated active Photodetection system type electronic switch, and it is used cold
Light source has infrared light, red light, green light and blue light etc., can be non-contact, rapid with no damage and the various solids of control, liquid
The state of the materials such as body, the transparent body, black matrix, flexible body and smog and action.It is low, smart response speed to be present in contact travel switch
The shortcomings of degree is poor, contact detection is easily damaged detected material and short life, and the operating distance of transistor proximity switch is short, it is impossible to
Directly detect nonmetallic materials.But novel photoelectric switch then overcomes their disadvantages mentioned above, and small volume, function it is more,
Long lifespan, precision height, fast response time, detecting distance is remote and anti-light, electric and magnetic interference ability is strong.
This new optoelectronic switch has been used as Level measurement, Liquid level, product counting, width differentiation, speed inspection
Survey, cut-to-length, hole identification, signal delay, automatically-controlled door sensing, colour code detection, punch press and cutter and security protection etc.
Numerous areas.In addition, using the disguise of infrared ray, can also be in the field of bank, warehouse, shop, office and other needs
Cooperate to be used for anti-stealing warning.
Switching Power Supply is to utilize modern power electronics technology, the time ratio that controlling switch pipe turns on and off, and remains steady
Determine a kind of power supply of output voltage, Switching Power Supply is typically by pulse width modulation（PWM）IC and MOSFET is controlled to form.Switch electricity
Source is compared with linear power supply, and the cost of the two all increases with the increase of power output, but the two rate of rise is different.Linearly
Power supply cost is on a certain power output point, and on the contrary higher than Switching Power Supply, this point is referred to as cost rollback point.With power electronics
The development and innovation of technology so that switch power technology is also innovated constantly, and this cost rollback point is increasingly to low output electricity
Power end is moved, and this provides wide development space for Switching Power Supply.
Switching Power Supply high frequency is the direction of its development, and high frequency minimizes Switching Power Supply, and enters Switching Power Supply
Wider application field, the particularly application in high-technology field, minimizing, being light for new high-tech product is promoted
Change.The development of other Switching Power Supply and apply save the energy, economize on resources and environmental protection in terms of all have great importance.
The power electronic devices applied in Switching Power Supply is mainly diode, IGBT and MOSFET.SCR is in Switching Power Supply input rectifying electricity
There is a small amount of application in road and soft starting circuit, GTR drivings are difficult, and switching frequency is low, is gradually substituted by IGBT and MOSFET.
