Description
Technical field
This utility model relates to a kind of motor protection device used for cooling tower.
Background technology
Motor damage that mainly winding is overheated or insulating properties reduce and cause, and the overheated of winding flows through often
The electric current of winding is excessive to be caused.Protection to motor mainly has electric current, the big type of temperature detection two.
Thermorelay utilizes load current to flow through the resistive element of calibration, produces curved after making Bimetallic thermal element heating
Song, so that the action before motor winding burns out of the contact of relay.Its acting characteristic and the permission of motor winding
Load characteristic is close.Though thermorelay accuracy movement time is general, but motor can be realized effective overload protection.With
Constantly improving of structure design, in addition to having temperature-compensating, it also has open-phase protection and laod unbalance protection merit
Can etc..The T series Double-metal-sheet type thermal over-loading relay such as introduced from ABB AB；3UA5,3UA6 system introduced from Siemens
Row Double-metal-sheet type thermal over-loading relay；JR20 type, JR36 type thermal overload relay, wherein Jn36 type is secondary development product,
May replace obsolete product JRl6 type.Motor protection chopper hot type with thermo magnetic trip release is used as overload protection, structure
And the same thermorelay of operating principle, have after the bending of its Bimetallic thermal element directly pushes up trip gear, and have makes contacting,
After cause chopper to disconnect.The setting valve of electric magnet is higher, only the action when short circuit.Its simple in construction, volume are little, price is low,
Acting characteristic conforms to current standards, protects reliably, therefore is used the most in a large number. and particularly low capacity chopper is especially pronounced.
The M611 type motor protection chopper such as introduced from ABB AB, domestic DWl5 low pressure universal circuit breaker (200
630A), S series breaker of plastic casing (100,200,400 enter).
Current existing motor protection device structure used for cooling tower is complicated, and stability is relatively low, in-convenience in use.
Utility model content
The technical problems to be solved in the utility model is to provide one and avoids overload, and compact conformation, structural stability is high
Motor protection device used for cooling tower.
For solving the problems referred to above, this utility model adopts the following technical scheme that
A kind of motor protection device used for cooling tower, including yoke, iron core, coil and support, described iron core is located in yoke,
Described iron core is fixing with yoke to be connected, and described coil is located at outside iron core, and described is erected at yoke side, described support and magnetic
Yoke welds, and described support is provided with bolt, and described bolt is disposed with armature and adjusting nut, described adjusting nut with
Bolt thread connects, and described yoke top is provided with regulation screw, and described regulation screw is threadeded with yoke, described armature end
End is provided with push rod, is provided with break contact and moving together contact, is provided with rubber washer in the middle part of described armature below described push rod,
Described rubber washer is connected with armature gluing.
As preferably, the L-shaped setting of described support, keep easy for installation, reduction takes up room.
As preferably, described iron core diameter is more than 1cm, keeps producing bigger magnetic induction.
As preferably, described bolt is provided with spring, holding armature Stability Analysis of Structures.
As preferably, described yoke is stalloy yoke, keeps magnetic line of force laser propagation effect good.
As preferably, described yoke thickness is more than 2cm, keeps magnetic line of force laser propagation effect good.
As preferably, described regulation screw length is more than 1.5cm, keeps range of accommodation wide.
As preferably, the U-shaped setting of described yoke, holding Stability Analysis of Structures is reliable.
The beneficial effects of the utility model are: the coil of setting is when current overload, and electromagnetic attraction is more than the anti-work of spring
