Also include radiating subassembly, described radiating subassembly include being located in pedestal and along the extension of base length direction radiator with
And connection row, described radiator communicate with the external world, described connection row is for the connection between radiator and busbar.
In the specific embodiment of the present invention, the length of described breaker, link block and contactor along pedestal
Spend direction to arrange, the described pedestal groove spaced apart in the longitudinal direction being provided with for housing the radiator, the two of the groove
End is respectively arranged with the steam vent communicated with outside.
In another specific embodiment of the present invention, described pedestal is set respectively in the both ends end of length direction
There is the exhaust outlet communicated with steam vent.
In another specific embodiment of the present invention, described steam vent has a bending in the longitudinal direction.
In another specific embodiment of the present invention, described radiating subassembly also includes the capping that section takes the shape of the letter U, institute
The radiator stated is contained in the U-shaped cavity of capping, and the fin below radiator is resisted against on the bottom surface of groove.
The present invention's and then in a specific embodiment, described being sealed on the bottom wall of U-shaped cavity offers use
In the notch connected for connection row with radiator.
In a still more specific embodiment of the invention, on described notch it is extended have for connection discharge into row every
From division board.
The present invention is timely by caused heat on busbar by cross-ventilation due to having additional radiating subassembly on pedestal
Outwardly discharge, so as to reduce the temperature rise of busbar, reduce influence of the busbar temperature rise to current transformer, ensure electric current
The characteristic of transformer will not have an impact, and make its more preferable, more reliable and more efficient work of energy under long-term use.

Embodiment
In order that the public can be fully understood by the technical spirit and beneficial effect of the present invention, applicant will be below with reference to accompanying drawing
The embodiment of the present invention is described in detail, but description of the applicant to embodiment is not the limitation to technical scheme, is appointed
What is changed in the form rather than substance according to present inventive concept should all be considered as protection scope of the present invention.
The concept of the every directionality for being related to upper, lower, left, right, front and rear or directionality is all in the following description
On the basis of the position shown in Fig. 1, thus it can not be understood as being particularly limited to technical scheme provided by the invention.
The present invention relates to a kind of control and protective switch, such as Fig. 1 to Fig. 5, including pedestal 4, the open circuit on pedestal 4
Device 1, contactor 2 and link block 3, described link block 3 between described breaker 1 and described contactor 2, and
And the link block 3 is realized and electrically connected with breaker 1, contactor 2 respectively by busbar 31 thereon.
Technical essential as technical scheme provided by the invention：Also include radiating subassembly 5, described radiating subassembly 5 wraps
Include and be located in pedestal 4 and the radiator 51 along the extension of the length direction of pedestal 4 and connection row 52, described radiator 51 with
