出廠測試 

型式試驗的目的是驗證定型的配電箱的設(shè)計性能是否符合本企業(yè)標(biāo)準(zhǔn)要求。

型式試驗是新產(chǎn)品試制投產(chǎn)必須進行的試驗。只有當(dāng)產(chǎn)品設(shè)計、制造工藝、使用原材料或零部件結(jié)構(gòu)有更改，可能影響配電箱防爆性能時，才需要重新進行有關(guān)項目的型式試驗。正常生產(chǎn)的產(chǎn)品每隔五年進行一次。任一型式試驗的試品，從出廠檢驗合格的產(chǎn)品中，任意抽取2臺進行試驗，2臺試品試驗都合格，才能認(rèn)為型式試驗合格。否則必須分析原因，采取技術(shù)措施甚至改進設(shè)計、工藝等再重新進行試驗，直到型式試驗合格為止。

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.

安裝方法

1.安裝使用產(chǎn)品前應(yīng)檢查銘牌上的技術(shù)數(shù)據(jù)與使用情況是否相符；

2.安裝及維修前必須切斷前級電源；

3.進、出線電纜穿過橡膠密封圈，須用墊圈及壓緊螺母壓緊，保證密封及電纜不得松動；

4.密封圈在使用過程中出現(xiàn)腐蝕、脆裂、變形、發(fā)粘或硬度變化超過出廠時的20%應(yīng)及時向廠家進行選購并更換，      以確保防爆性能可靠；

5.維護拆卸時注意隔爆面不得磕碰、劃傷、腐蝕，并定期涂204-1防銹油；

6.配電箱在使用過程中要定期檢查，以保證其良好運行；

7.非專業(yè)人員嚴(yán)禁開蓋維修、檢查。

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.
