出厂测试 

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最大分断时间试验；

l) 脱扣器动作特性试验；

m) 额定短路分断能力试验。

The factory test

Type test is to verify the purpose of shape design of distribution box performance conform to the enterprise standard requirements.

Type test is a new product trial production test must be conducted. Only when the product design, manufacturing process, the structure of the use of raw materials or components are subject to change, may affect the distribution box, explosion-proof performance need to re-run the type testing of the project. Normal production of a product every five years. Try any type of product from the factory inspection qualified products, any makes a test of two (2) 2 sets of test product is unqualified, to that type of test. Otherwise have to analyze the reason, technical measures and even improving design, process, such as test again, until the type testing qualified.

Type test project:

A) all the factory inspection project.

B) the temperature rise test, temperature test;

C) shell and transparent impact test;

D) transparent heat test and cold test;

E) elastic sealing ring material aging test;

F) cable entry device clamp test;

G) explosion-proof casing pressure test;

H) explosion-proof enclosure internal testing not explosive lighting;

I) shell protective ability test;

J) operating performance test;

K) leakage circuit breaker rated residual operating current, rated residual operating current not the biggest breaking time test;

L) trip movement characteristic test;

M) rated short circuit breaking capacity test.

安装方法

1.安装使用产品前应检查铭牌上的技术数据与使用情况是否相符；

2.安装及维修前必须切断前级电源；

3.进、出线电缆穿过橡胶密封圈，须用垫圈及压紧螺母压紧，保证密封及电缆不得松动；

4.密封圈在使用过程中出现腐蚀、脆裂、变形、发粘或硬度变化超过出厂时的20%应及时向厂家进行选购并更换，      以确保防爆性能可靠；

5.维护拆卸时注意隔爆面不得磕碰、划伤、腐蚀，并定期涂204-1防锈油；

6.配电箱在使用过程中要定期检查，以保证其良好运行；

7.非专业人员严禁开盖维修、检查。

Installation method

1. Install the check before use the product technical data and the use situation of the nameplate of match;

2. Installation and maintenance must be cut off before the level power supply;

3. The inlet and outlet cable through the rubber sealing ring, must use washer and gland nut pressure, ensure sealing and cable must not loose;

4. The sealing ring in use process, corrosion, deformation, sticky or hardness changes more than 20% of the factory is to be in a timely manner to the manufacturer and replacement of choose and buy, in order to ensure reliable explosion-proof performance;

5. Maintenance is disassembled note flame-proof surface may knock against, scratches, corrosion, rust-proof and regularly with 204-1;

6. Distribution box in use process, should be inspected regularly to ensure its good operation;

7. Inspection maintenance, non-professional personnel are strictly prohibited to open cover.
