Description
Technical field
This utility model relates to the contactor arrangement field of distributor, is specifically related to a kind of for distributor
Push button catalyst.
Background technology
Catalyst is divided into A.C. contactor (voltage AC) and D.C. contactor (voltage DC), and it is applied to
Electric power, distribution and electricity consumption.Catalyst broadly refers to utilize coil to flow through current induced magnetic field in industrial electro,
Make contact closure, to reach to control the electrical equipment of load.Often apply to motor also may be used as control object
Being used as to control the electrical load such as shop equipment electric heater machine-tool and various kinds electric power unit, catalyst is not
It is only capable of being switched on and off circuit, but also there is low-voltage release guard effect.Catalyst control capability is big,
It is applicable to frequent operation and distant control, is one of critical elements in automatic control system.At a distance
During control, catalyst energising is resumed work, and dependence automatically controls, but sometimes for directly cutting off the electricity supply, mesh
Front catalyst controls inconvenience.
Utility model content
The purpose of this utility model is that provides a kind of button for distributor to solve the problems referred to above
Formula catalyst.
This utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of push button catalyst for distributor, including protection against electric shock shell, arc-extinguish chamber, armature, electromagnetism
Coil, described protection against electric shock shell upper is provided with button, is provided with described arc-extinguish chamber, institute below described button

Help and below contact, be provided with normally opened auxiliary contact, below described normally opened auxiliary contact, be provided with described armature, institute
Stating and be provided with static iron core below armature, described armature is internally provided with spring, and described static iron core is internally provided with
Described solenoid, described solenoid bottom is provided with binding post.
In said structure, when, after solenoid energising described in catalyst, described solenoid will produce magnetic field,
Described normally closed auxiliary contact disconnects, and described normally opened auxiliary contact close, it is achieved circuit controls, when needs are direct
When cutting off the electricity supply, manual operation, described protection against electric shock can be carried out by the break-make of described button control circuit
Shell can effectively ensure operator safety, provides convenience for work to a certain extent.
In order to improve its using effect further, described button is connected with described protection against electric shock shell, described master
Contact outer cover has described arc-extinguish chamber.
In order to improve its using effect further, described normally closed auxiliary contact connects with described normally opened auxiliary contact
Touching, described armature contacts with described static iron core.
In order to improve its using effect further, described spring is connected with described solenoid, described wiring
Post is connected with described solenoid.
Have the beneficial effects that: this catalyst can carry out manual operation when necessary, simple to operate, Ke Yizhi
The cut-out of connection control circuit, it is possible to the safety of operator is effectively ensured.
Accompanying drawing explanation
Fig. 1 is the topology view of a kind of push button catalyst for distributor described in the utility model.
1, binding post；2, static iron core；3, solenoid；4, spring；5, armature；6, normally opened auxiliary is touched
Point；7, normally closed auxiliary contact；8, main contacts；9, arc-extinguish chamber；10, button；11, protection against electric shock shell.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings:
As it is shown in figure 1, a kind of push button catalyst for distributor, including protection against electric shock shell 11, arc extinguishing
