Alternating current circuit protection is used.That is：In electrical equipment and turnaround of unit work and shut-off, switch has fuse disconnecting switch
Obvious cut-off point, play isolation voltage and emergent disconnection effect, during the normal work that closes a switch, fuse disconnecting switch
It is used as overload and short-circuit protection in alternating current circuit（Suitable for the power distribution circuit of high short circuit current）, existing static contact passes through
Two left and right static contact connections, when it is by relatively large electric current, caused heat is big, while thermal diffusivity is weaker, peace be present
Full hidden danger, thus may trigger accident, and security performance is low.
The content of the invention
The purpose of the utility model is：One kind is provided to be not only simple in structure, be easy to use, and good heat dissipation effect, security
Can be high, while suitable for the disconnecting switch static contact group of high current.
The technical solution of the utility model is：A kind of disconnecting switch static contact group, including contact knife slot are located at same
The first static contact, the second static contact, the 3rd static contact on straight line；
First static contact, the second static contact, the 3rd static contact include connecting plate, are vertical at the connecting plate one
The left and right static contact at end, and for the left and right static contact to be pressed against to the holddown spring of fuse connection end both sides；Together
The static contacts of Shi Suoshu first, second static contact, the connecting plate of the 3rd static contact are superimposed setting, this practicality from top to bottom
It is new to be connected using the first static contact, second static contact, the 3rd static contact with fuse connection end, contact effect
It is good, and gap between the first static contact, second static contact, the 3rd static contact be present, it is easy to radiate.
As preferable technical scheme, it is provided with the left and right static contact and positioned at contact knife slot both sides and is used to install
The reinforced wall of holddown spring, positioning jack is provided with the reinforced wall, is easy to holddown spring to fix.
As preferable technical scheme, the first static contact, the second static contact, the 3rd static contact connecting plate on and it is remote
One end from left and right static contact is provided with end of incoming cables mounting hole.
As preferable technical scheme, on the connecting plate, extend away from left and right static contact one end both sides and widen side
The wing, the width of current output terminal is added, improve output current.
As preferable technical scheme, the disconnecting switch is installed on insulator foot with static contact group, while the company
The insulator foot is extended in the one end of fishplate bar away from left and right static contact, further improves radiating effect.
As preferable technical scheme, the left and right static contact, the connecting plate use thickness purple for 4mm tabular
Copper.
The utility model has the advantages that：
1. the utility model is not only simple in structure, is easy to use, and using the first static contact, second static contact,
3rd static contact is connected with fuse connection end, and contact effect is good, while the first static contact, second static contact, institute
State between the 3rd static contact and gap be present, be easy to radiate, pass through suitable for high current, security performance is high.
Brief description of the drawings
Below in conjunction with the accompanying drawings and embodiment is further described to the utility model：
