JKW58 series reactive power auto compensating cont

JKW58 series reactive power auto compensating controller Operation Manual Instruction A. High compensation precision for counting capacity of capacitor by reactive power; B.High power factor of measuring precision, wide display area; C.With automatic distinguish function, automatically keep the voltage signal and current signal in the same terminal; D.With two working modes of full-automatic and handwork set; E.Friendly human-computer interface, easy to operate; F.Different controlling parameter is adjustable in whole digit; it is easy to use at direct-viewing; G.With two working modes of auto and manual operation; H.With the protecting function of overvoltage and overcurrent; I.With the power down function, so the data cannot lose; J.With low impedance(≤0.01). 1.Introduction JKW58 series reactive power auto compensating controller is suitable for self-adjusting capacitor Compensating devices in low voltage distribution system and make power factor meet with presetting set by user, therefore it will increase the efficiency of the power transformer, reduce line loss, and improve voltage quality. On final aim it will increase the economic and social benefits. 2.Ambition conditions a.Altitude not more than 2500m. b.Ambient temperature:-25°C 50°C c.Relative humidity:<50% at 40°C and <90% at 20°C d.On site where it has no corrosive gases, conductive dusts, combustible explosive mediums. e.On site where it has severe vibration. 3.Technical specifications Rated working voltage; AC380V 50HZ Rated working current: AC 0 5A 50HZ Rated output power: AC220V 7A 50HZ Displaying power factor; Lag 0.001 forward 0.001 Measured capacity: 0 9999KVAR Working mode: automatic selecting the best or loop switch Sensitivity: 100mA Protection class: IP40 (outer enclosure) 4.Advice for Use The characteristics of full automatic working mode: This controller has been in the automatic mode before leaving factory. All parameter has been preset according to the most reasonable method. It works normally as long as users connect the wiring correctly. The characteristics of handwork setting mode: when the load is light at several fields ,and the capacity is big ,the controller goes on input and cut vibration continuously, under this condition ,the handwork setting mode is suitable for using. 5.Selection the full automatic and handwork setting mode Use the different #118alue of PR-4 parameter to distinguish and select the working mode of controller (see part 6)If user adjusts this parameter within (1-12),which means the controller is under the automatic mode. And the big and small data means how much the output loop of the controller is .If user adjusts this parameter within (50-40000,which means the controller is under handwork mode, the big and small data means the transformation ratio of user coefficient and total current mutual inductor. Note: before the controller is not used, the transformation ratio of the actual current mutual inductor and capacity parameter of all capacitor must be input to the controller under the handwork mode. 6.Menu Operation Operating the Menu Key in turn, the controller will enter into the menu of Power Factor, Reactive Power, Manual operation and Parameter preset circularly.Note:Only after entering into manual operation menu in 2 senconds.could the operation key Menu be entered into parameter adjustment menu. Other menus havent this limit. The reactive power menu will display the symbol AUTO under the full automatic mode. The parameter preset menu has submenu 16 items under handwork mode .Operating the Menu key in turn, enter into each of submenu separately. when operating the key of increasing and decreasing by degrees ,the target data of each submenu can be preset, and the four-position digitron displays Menu code and target data alternately. For example:PR-1 means menu code ,098 means target data. The parameter preset menu has submenu 4 items under full automatic mode, that is Power Factor Preset. Delay Preset, Overvoltage preset, Loop preset (preset menu of transformation ratio of public current mutual inductor) 7.Code meaning of submenu under the parameter preset menu: PR-1 target power factor preset (0.90-0.99) adjustable PR-2 Time Delay preset (static state 1S-200S) Adjustable PR-3 Overvoltage preset (400V-500V) Adjustable PR-4 Current transformation ratio preset (1-12)or (50/5A-4000/5A) 1-12 means output loop quantity of controller, full automatic mode. 50-4000 means transformation ratio at site total current mutual inductor, hand work input mode. C-01 capacity preset of No.1 capacitor group (0-150Kvar) capacity preset of No.12 capacitor group (0-150Kvar) Note : Code C-01,02,03..12 is one to one correspondence with the control output terminal code of the controller being used for controlling AC contractor. It should be one to one correspondence when input capacity of capacitor. For example, the capacity of capacitor group is 15 kilovar controlled by No.1 input terminal ,the target data of C-01 menu should be adjusted as 15. For the output terminal which is not connected with capacitor, the target date should be adjusted as0
