Abstract
The utility model relates to an alternating current vacuum starter with a multifunctional motor protector, which comprises a multifunctional motor protector and an alternating current vacuum starter which are organically combined. The multifunctional motor protector is positioned at the lower end of the alternating current vacuum starter, and a high capacity casing of the motor protector is integrally connected with a casing of the alternating current vacuum starter. The alternating current vacuum starter with a multifunctional motor protector has the advantages that the multifunctional motor protector and the alternating current vacuum starter are organically combined, thereby eliminating the drawbacks of long wire, multiple junctions due to far distance from the protector to the starter, which results in waste of energy and materials, and further facilitating installation and maintenance.
Description
Technical field
The utility model relates to a kind of AC vacuum starter, is specifically related to be equipped with the AC vacuum starter of multi-functional electric motor protecting device.
Background technology
In the prior art, the many kinds of motor protecters that three-phase alternating-current motor phase shortage, overload etc. are shielded are arranged, but the function of these protectors is complete inadequately, is subject to external circuitry and disturbs, easily misoperation.
In the prior art, motor protecter does not have beepbox, overcast and rainy danger, and hidden danger is big.In the prior art, most of motor protecters all with the partial installation of AC vacuum starter, the disadvantage that lead that protector and starter distance cause is long, contact is many and the energy that therefore causes, the waste of material, make install and maintenance all very inconvenient.
In the prior art, AC vacuum starter upper wiring board all adopts two fixed screws, and is easily loosening, is easy to generate the problem of virtual connection.
In the prior art, the AC vacuum starter adopts the AC excitation type of drive.AC excitation drive have that pull-in winding adhesive shake, coil holding current are big, major loop contact adhesive instability, the hum noise is big, coil easily burns problem.
In the prior art, the AC vacuum starter does not have the communication function, and structure control is single, can't realize networking.
The utility model content
The purpose of this utility model is the above-mentioned shortcoming that overcomes AC vacuum starter and motor protecter in the prior art, and the utility model is achieved by following several respects: described AC vacuum starter comprises multi-functional electric motor protecting device and AC vacuum starter.It organically combines multi-functional electric motor protecting device and AC vacuum starter.The multi-functional electric motor protecting device is positioned at the lower end of AC vacuum starter; the big capacity housing of motor protecter and the housing of AC vacuum starter connect into as a whole; be provided with the partition panel of insulation in the housing between multi-functional electric motor protecting device and the starter; have the strip hole on the surface of partition panel; the following terminal block of starter passes the strip hole; and the bottom end cover that passes motor protecter stretches out outside the lower end of motor protecter; the surface, lower surface of partition panel is provided with insulating case; insulating case is enclosed within down on the outer surface of terminal block, and the signals collecting coil of multi-functional electric motor protecting device is enclosed within on the outer surface of insulating case.Microcomputer silencing energy economizer drive unit is equipped with in the rear end on the AC vacuum starter.Be designed to the screw location hole of isosceles triangle at the upper wiring board place of AC vacuum starter.On the bottom end cover of multi-functional electric motor protecting device, be equipped with to shake to control and import mouth and control operation line interface into.
Another specific embodiments of the present utility model is that the housing (4) of multi-functional electric motor protecting device (1) is injection molded into as a whole with the housing (3) of AC vacuum starter (2).
Another specific embodiments of the present utility model is that described a kind of AC vacuum starter with the multi-functional electric motor protecting device is injected with partition panel (5) between housing (3) or (4), and has strip hole (6) on the surface.
Another specific embodiments of the present utility model is, described a kind of AC vacuum starter with the multi-functional electric motor protecting device, and microcomputer silencing energy economizer drive unit (11) is equipped with in the last rear end of AC vacuum starter (2).
Another specific embodiments of the present utility model is that described a kind of AC vacuum starter with the multi-functional electric motor protecting device is equipped with to shake to control on the bottom end cover (8) of multi-functional electric motor protecting device (1) and imports mouth and control operation line interface (12) into.
Another specific embodiments of the present utility model is, described a kind of AC vacuum starter with the multi-functional electric motor protecting device has the screw location hole (12) of isosceles triangle at the upper wiring board place of AC vacuum starter (2).
Useful technique effect of the present utility model is; because this real utility model combines multi-functional electric motor protecting device and AC vacuum starter; eradicated the disadvantage that lead is long, contact is many that protector and starter distance cause and the energy that therefore causes, the waste of material, make install and maintenance all very convenient.The multi-functional electric motor protecting device is on line design; adopted strong and weak electricity to use the design of two circuit boards respectively; strong and weak electricity is fully separated; in the peripheral circuits of ATMEL89S52 chip and triggering starting circuit, added jamproof buffer circuit; make the more reliable and more stable work of protector, avoided the shortcoming of protector misoperation.This reality is novel has set up beepbox and network communication device and has eradicated and can't realize long-range drawback of shaking control and network communication.And the AC vacuum starter is designed to be the three-point fix of isosceles triangle with the stationary positioned screw of the upper wiring board of three vacuum tubes, makes the fixing more reliable of conductive plate, avoided that conductive plate is easily loosening, the problem of virtual connection.Change traditional AC excitation type of drive, and adopted more energy-conservation, reliable DC excitation type of drive.380 volts of power supplies are converted into 55 volts, 34 milliamperes direct current by energy-conservation noise reduction DC excitation electronic circuit is the pull-in winding power supply, thus solved AC excitation drive pull-in winding adhesive shake, coil holding current greatly, major loop contact adhesive instability, the hum noise is big, coil easily burns problem.Thereby realized the adhesive non-jitter, the coil holding current is little, the adhesive of major loop contact is reliable and stable, noiselessness, coil long service life.
