防爆配电箱型式试验

型式试验的目的是验证定型的配电箱的设计性能是否符合本企业标准要求。
型式试验是新产品试制投产必须进行的试验。只有当产品设计、制造工艺、使用原材料或零部件结构有更改,可能影响配电箱防爆性能时,才需要重新进行有关项目的型式试验。正常生产的产品每隔五年进行一次。任一型式试验的试品,从出厂检验合格的产品中,任意抽取2台进行试验,2台试品试验都合格,才能认为型式试验合格。否则必须分析原因,采取技术措施甚至改进设计、工艺等再重新进行试验,直到型式试验合格为止。
  型式试验项目:
a) 所有出厂检验项目;
b) 温升试验、温度试验;
c) 外壳和透明件冲击试验;
d) 透明件耐热试验及耐寒试验;
e) 弹性密封圈材料老化试验;
f) 电缆引入装置夹紧试验;
g) 隔爆外壳耐压试验;
h) 隔爆外壳内部点燃的不传爆试验;
i) 外壳防护能力试验;
j) 操作性能试验;
k) 漏电断路器额定剩余动作电流,额定剩余不动作电流的*大分断时间试验;
l) 脱扣器动作特性试验;
m) 额定短路分断能力试验。

Explosion-proof distribution box type test

The purpose of the type test is to verify design performance stereotypes distribution box meets the standard requirements of the enterprise .
Type test is to test new product trial production must be carried out . Only when the product design , manufacturing processes, use of raw materials or components structure changes that may affect the distribution box explosion-proof performance , only need to re- type test of the projects . Normal products once every five years . Any type test sample from the factory inspection of products, the random selection of two test , two sample tests are qualified to consider the type test qualified. Otherwise, you must analyze the causes and take technical measures to even improve the design, technology and other re- test until the type test so far.
  Type test items:
a) All factory inspection program ;
b) temperature rise test , temperature test ;
c) impact test pieces of shell and transparent ;
d) transparent pieces of heat and cold test test ;
e) an elastic ring material aging tests ;
f) cable entry clamp test ;
