GCK低壓抽出式成套開關(guān)設(shè)備主要特點(diǎn) Main feature
1. GCK1、GCJ1 為拼裝式組合結(jié)構(gòu)，基本骨架采用專用型材，拼裝而成。
2. 柜體骨架，零件尺寸以及開孔尺寸按基本模數(shù)E=25mm 變化。
3. 在MCC 方案中，柜內(nèi)部分成五個(gè)區(qū)域（室）：水平母線區(qū)、垂直母線區(qū)、功能單元區(qū)、電纜室、中性接地母線區(qū)。各區(qū)互相隔離，保證線路正常運(yùn)行，有效防止故障擴(kuò)大。
4. 由于框架的所有結(jié)構(gòu)均以螺釘緊固連接而成，避免了焊接變形和應(yīng)力，提高了精度。
5. 零部件通用性強(qiáng)，適用性好，標(biāo)準(zhǔn)化程度高。
6. 功能單元（抽屜）的抽出、插入為杠桿操作，加上配置滾動(dòng)軸承操作輕便、可靠。
1. GCK1 and REGCJ1 are assemble type combined structure. The basic skeleton is assembled by adopting special bar steel.
2. Cabinet skeleton, component dimension and starter size change according to basic modulus E=25mm.
3. In MCC project, parts in cabinet are divided into five zones (compartment): horizontal bus bar zone, vertical bus bar zone, function unit zone, cable compartment, and neutral earthing bus bar zone. Each zone is separated mutually for circuit’s normal running and effectively preventing fault expansion.
4. As all structures of framework are connected and firmed by bolts, so it avoids the welding distortion and stress, and upgrades the precision.
5. Strong general performance, well applicability and high standardization degree for components.
6. Draw-out and insert of function unit (drawer) is lever operation, which is easy and reliable with rolling bearing.
