SBTW1 series
Intelligence style frame turnoffs utensil
■scope of application
SBTW1 series intelligent omnipotent style depression turnoff utensil ( Below for short turnoff utensil) . Fitting be used for communicate 50Hz. Rated voltage 400V. 690V. Current rating for 400A — 6300A will distribute in network. Chief be used for allot electric energy and guard wire and current supply device free from overload. Owes voltage. Short. Single-phase contacts to earth wait for breakdown’s harm. Should turnoffs utensil possess many kinds intelligences protect function. Can do selective protection. And action precisely. Avoids no need power cut. Enhances supply electricity credibility

Will be 3. Uses environmental condition
3.1 Surrounding air temperature
3.1.1 Upper limit value not does exceed + Will be 40 ℃
3.1.2 Lowest limit value not does under - Will be 5 ℃
3.1.3 24h ’s mean value not does exceed+ Will be 35 ℃
Note: Lowest limit worths for- Will be 10 ℃ or- Will be 25 ℃ ’s operating condition. Must to factory declare at order time consumer.
Upper limit worths exceed+ 40 ℃ or lowest limit will worth under- Will be 25 ℃ ’s operating condition. Consumers should
with factory negotiation.
3.2 Installation site’s height not exceed 2000m
3.3 Decent condition:
Atmosphere comparative absolute humidity around air humidity for+ 40 ℃ time not will exceed 50%. At compares can have compare high comparative absolute humidity under low temperature. Most fitting lunar monthly average most big comparative absolute humidity is 90%. Meanwhile should lunar monthly average minimum temperature for+ 25 ℃. And considers go because temperature change take place ’s congeal dew at product seemingly.

4.3 intelligent trips utensil ’s protect performance
4.3.1 trips utensil category: Possess can only type trip utensil. Owes voltage instantly ( Or delay) Action trip utensil and dispart encourage trip utensil
4.3.2 intelligent trips utensil performance
a. Possesses overload long delay inverse time limit. Short delay inverse time limit. Short delay fix time limit. Will move all sorts of function. Can by consumer by oneself enactment. Composes need ’s protect characteristic;
b. Single-phase ground protection characteristic;
c. Shows function: Punishes fix current Ir show. Action current shows;
d. Ammeter function: Checkouts main loop current;
e. Calls the police function: Overload call the police;
f. Self-checking function: Overheating protection. Micro computer since consultation;
g. Experiments function: Experiments trip utensil ’s action characteristic.
Note: Consumers need. Can ha communication joint ’s turnoff utensil. In by computer to turnoff utensil carry out remote control at one kilometre. Shake transfer. Measure from remote. |
