Product Description

Product Description

FZRN25-12D/T630-20 type indoor AC HV load switch is an indoor device of three-phase AC 50Hz and rated voltage 12K.It is applied to the sites of distribution substation of industrial and mining enterprises and substation etc, used for protecting and conteolling electric facilities,on and off load current, closed lop current,zero load transformer and cable charging current.
Equipped with manual and electromotive actuating mechanism,it is easy to realize the three remote control requirements for electric system.
FZRN25-12D/125-31.5 type indoor AV HV load switch -fuse combined electrical equipment is an indoor device of three-phase AC 50Hz and rated voltage 12KV.It is applied to the sites of distribution substation of industrial and mining entrtpriese and substation etc,used for load control and short circuit protection.The equipped ground switch can bear short circuit current.The manual and electromotive actuating mechanism for electric system.
FZN25-12D and FZRN25-12D type load switch and combined electrical equipment are applied to the urban areas distribution substation substation of three-phase ring net or rerminal supply and industrial electric devices,used for load control and short circuit protection.As the combined electrical equipments bring more reliable and economic protection functions to transformer etc electriacal devices,so it is especially applied to ring net,duble radiation supply unit and box type substation

Product technical parameters and external dimensions

Product Structural features and working principle

1. The product uses vacuum interrupter. Its performance is stable and reliable, with long electrical life, high breaking capability, strong making/breaking ability and easy to be operation and maintenance.
2. It combines switch body and operating mechanism, which integrates disconnector, load break switch and earthing switch. It is compact and with small volume.
3. Tandem arrangement of direct-acting isolating fracture and vacuum interrupter, high dynamic and thermal stable current; it can be operated at one time due to unique linkage operating procedures.
4. Structure of cone fixed contact, insulation cover and shutter can separate busbar and load break switch unit completely.
5. Vacuum load break switch, earthing switch, shutter, switchgear door are in accordance with "5 prevention" mechanical interlock, which can prevent misoperation and is safe and reliable.
6. Charged energy by spring operating mechanism, can closing and opening by electrical and by manual.
7. Operating voltage of closing and opening can be DC and AC.
8. The normal type is operated by left and right side operating mechanism, but can with front operating mechanism as user's requirement.
