Features 1.1, the core part is a computer, a powerful data acquisition and processing functions, the sensor secondary signal without any deformation processing, high-speed sampling and paid into the calculation, continuous quantitative processing of the information closest to the real case. 1.2, the use of crystal timing, all definite time, inverse time delay be accurate. 1.3, the use of microprocessor technology, be able to complete the aggregate, sub-gate control, overload, short circuit, leakage lockout, leakage protection, selective leakage protection, phase unbalance, undervoltage, wind power lockout, the cause of the fault memory query, networking communications, power metering and other functions. 1.4, full Chinese display, three buttons do not have to open the cabinet door can achieve all of its parameters to set and query are displayed in Chinese. Just as you click the mouse to operate the PC as easy and intuitive. 1.5, 10-bit A / D signal acquisition, significantly improve the measurement accuracy. 1.6 calculated using the root-mean-square value measurement of AC current and voltage measurement accuracy can be guaranteed, even if the power waveform serious interference case. 1.7, has a powerful memory function: A record total working hours up to a maximum of 1 million hours; B records the cumulative number of closing up to 100 million times; C record kilowatt up to 100 million degrees; The above data automatically after the expiry of overflow, with blackout protection of 40 years. D Protect 100 failure records available for inspection, can record the date and time of the cause of the malfunction and failure (month, day, hour, minutes), the last-in, first-out order, and automatic numbering, note 100 will Auto Clear 98 records. 1.8, with the exact date when the drill function, the lowest line of the LCD screen displays the current drill: month, day, hour, minute, second, by pressing a button to adjust. Equipped with a backlit LCD screen, especially eye-catching in the dark to make your a visible current work status. 1.9, users need a special designated RS485 communication function, then only 2 to 999 protection can be linked into the network, access to the LAN or Internet by coupling. Note: It is best to use the factory computer communication software! Otherwise, the network side communication protocols to us, or in the original network the same hardware, the software used directly to our plant. 2, function ZLDB-5T-type protection device has the following 16 basic functions 2.1 the feed switch load side short-circuit fault, the the timing speed limit break protection. 2.2, continued on the the feed switch the load side of the overload, the implementation of anti-time protection and alarm. 2.3, the load side of the feed switch intermittent overload, energy release and accumulation operations, the implementation of anti-time protection. Overload alarm. 2.4, leakage lockout protection: insulation resistance is lower than on the the feed switch load side of the load, 40k ohm pull-up resistors +20% (1140V), 22K +20% (660V) 7KΩ +20% (380V) can reliably achieve leakage lockout. 2.5, leakage protection: the protector is playing in the position of the master switch, if the primary path is leakage or branch line leakage long time, the master switch will trip within the set time. Leakage protection action were: as 20k. (1140V), 11KΩ (660V) and 3.5KΩ (for 380V). 2.6, selective leakage protection: protection of playing in the sub-switch position if the branch leakage phenomenon, the branch switch will trip, and the other branch switches and switches are not tripped. Selective leakage protection action value: 5KΩ ~ 20KΩ (for 1140V), 5KΩ ~ 13KΩ (for 660V) and 3K to 7KΩ (for 380V). 2.7, taken when the line voltage is less than the set undervoltage protection. 2.8 Chinese characters display the current grid voltage load current value, to protect the cause of the action. 2.9, the reason for the trip long-term memory (again and again), a detailed record of 20 times before the fault trip reason. 2.10, records the cumulative number of points closing cumulation electricity consumption, total working time. 2.11, with an Analog the fault test self-test function, to ensure that their own without the trouble-free operation. 2.12, spreadsheet functions, precise positioning of working hours. 2.13, wind power blocking function. 2.14, phase equilibria protection: three-phase three-phase load the check phase loss protection, you can choose to open and close. 2.15, secondary password function to prevent unrelated personnel to operate the password feature can be set to turn on and off. 2.16 Unless otherwise specified with the protection of the communications network function: to the higher station transmits real-time kilowatt grid voltage, load current, insulation resistance, closing the case, the state of alarm and fault trip reason; through the PC remote control parameter tuning, time setting, tuning of the extension, over-current test, leakage test, electric closing, and can upload protector tuning stalls. Specific information to be transferred, according to user requirements may be set up a special communication protocol. Tuning stalls. Specific information to be transferred, according to user requirements may be set up a special communication protocol. ☆ ☆ according to user requirements increase access special function is only for reference use ☆ ☆ ☆ ☆ ☆ ☆ electricity metering, the main technical parameters ZLDB-5T models using the function of the entire Chinese menu option file, the user through the feed switch box The two buttons on the door to all operations. (1), the voltage level: line voltage (V). Voltage tuning variable tranches. Nominal value of 660V, 1140V, use, based on the actual grid voltage select the correct display mode. (Example: If used to select the feed switch on 660V 660V display mode). Accuracy: +8%. (2) Rated current Ie Rated current setting variable tranches. 40A-400A nominal value of a very wide range of adjustment, step 5A users according to the actual load current, select the corresponding rated current file, if necessary, choose a little larger can. Transformer sub-file: 400A, 630A, according to the actual use of the transformer to select the appropriate gear. (3), overload 3.1, the load current exceeds the nominal value of the rated current at 1.1 times the alarm, and begin to implement the inverse time delay, the greater the load current exceeds a multiple of the rated current setting, the shorter the delay action.
