    • The subject of the invention is an electric power switchgear, an insulating radiator, and a method for installing the radiator in an electric power switchgear, and in particular in a medium or high voltage switchgear. The electric power switchgear comprising working elements placed in the housing (1) and connected with busbars (7a) and branches (7b, 7c, 7d), cooled with air supplied from outside in a natural or forced way, is characterised in that it contains at least one insulating radiator (11) made of thermoplastic material of increased thermal conductivity ? > 2VWmK1 which is placed in the electric field of the switchgear and which is connected by a non-permanent fastening to at least one busbar (7a) or/and at least one branch (7b,7c,7d). The insulating radiator designed for the switchgear as per the invention is an injection moulding including a base plate (12) to whose top face (13) a system of heat evacuating elements (14) of identical or diverse shape is attached, and to its side surfaces elastic assembly catches (15) are fixed.
    • 本发明的主题是电力开关设备,绝缘散热器和用于在电力开关设备中安装散热器的方法,特别是在中压或高压开关设备中。 电力开关设备包括放置在壳体(1)中并与母线(7a)和分支(7b,7c,7d)连接的工作元件,其以自然或强制的方式从外部供应的空气冷却,其特征在于它包含 至少一个隔热散热器(11)由热导率增加的热塑性材料制成? 放置在开关装置的电场中并且通过非永久性紧固连接到至少一个母线(7a)或/和至少一个分支(7b,7c,7d)上的2VWmK1。 根据本发明设计的用于开关设备的绝缘散热器是注射成型,其包括底板(12),其底面(13),具有相同或不同形状的排热元件(14)的系统附接到其侧面 表面弹性组件卡扣(15)固定。
