Chapter IV: Intelligent Fault Detector



Foreword:
As a new generation of intelligent SCR fault and bus temperature detector researched and developed for large rectifying (variable current) electrical equipment by means of modern electronics technology, BS-T1228-III has fault position display and light warning in the front panel and fault relay control output and fault remote transmission function in the real panel (communication with the host computer through 485) in case of detection equipment fault. With simple and easy use, this instrument may only be correctly wired according to the wiring diagram of each part at the rear of the detector.
Ⅰ.Functions
1. 108 normally open contacts for fault detection, including:
96 KP detection points
12 high bus temperature points
2. Fault position display

3. Light indication alarm in case of fault
4. Relay output control functions in case of fault
5. Fault position remote transmission function
Ⅱ. Description of monitoring point matrix wiring:
KP fault detector has up to 108 normally open contacts for monitoring, which are accessed in matrix mode in wiring. The method for access of the normally open contacts to the monitoring board terminal block is shown below.
1. Monitoring element:
The element has two wiring pins, assumed pin 1 and pin 2.
2.  Concatenated diode:

Connect a diode in only one pin (pin 1 or 2, one pin rather than pin 1) of each element and lead from one pin (pin not connected with the normally open contact) of the diode and one pin (pin not connected with the diode) of the normally open contact with two wires respectively, as shown in Figure 2 below.
3. Element arrangement in matrix mode:
3.1 Make 96 KP fault monitoring points and 12 temperature monitoring points into a matrix of 12 rows and 9 columns and make sure to connect the outgoing lines from one end of all diodes to the row lines and the outgoing lines from one end of the elements to the column line without mistakenly connecting.
3.2 Arrange all KP (ZP) monitoring elements in columns 1-8 and all temperature monitoring elements in the 9th column.
Figure 3 below shows the permutation and combination mode of 108 elements.
Ⅲ. Why to concatenate the diode:
1. Not concatenate diode:
Figure 4 is the wiring diagram without concatenated diode. According to this figure, if KP101 in the 10th row and 1st column, KP102 in the 10th row and 2nd column and KP111 in the 11th row and 1st column are damaged, KP112 in the 11th row and 2nd column is not changed. But the monitor detection results show that KP111 bad flexibility in the low 11th row makes the column line in the 1st column low. With KP101 bad flexibility, the low column line in the 1st column is transferred to the 10th row, the row line in the 10th row is low  and the column line in the 2nd column is low due to KP102 bad flexibility. The monitor detects that KP112 and subsequent elements (KP112 and subsequent elements may not be damaged actually) are damaged and obtains an error result.

2. Concatenate diode
Figure 5 is the wiring diagram with concatenated diode. According to this figure, if KP101 in the 10th row and 1st column, KP102 in the 10th row and 2nd column and KP111 in the 11th row and 1st column are damaged, KP112 in the 11th row and 1st column is not changed. But the monitor detection results show that the 11th row is low, KP111 damage and flexibility make the 1st row line low. With KP101 damage and flexibility, the low column line in the 1st column is transferred to the diode D101 concatenated. Due to the role of D101, the low signal is blocked and the row line in the 10th row is not low. In this time, the low signal is not transmitted to the column line in the 2nd column although KP102 damage and flexibility and the monitor detects KP112 without error results.
Ⅳ. Front Panel
The upper part of the front panel displays the detector model, the two nixie tubes in the left below the model display the row number of the fault element in the access of the detecting element according to the matrix method and one nixie tube in the right below the mode displays the column number of the fault element. Four circular window indicator lights from bottom to up below the element row nixie tube and column nixie tube are used for indication of single element damage, double element damage, damage of double elements on the same arm and high bus temperature fault. Two nixie tubes at the bottom of the front panel indicate the high bus temperature element position. The explanatory note expressing the nixie tube or indicator light meaning is printed below or in the right of each nixie tube or indicator light.
Ⅴ. Rear Panel
There are three rows of binding posts on the rear panel of BS-T1228-III intelligent fault detector. In 14 binding posts in the left row, the upper 5 binding posts are fault relay output terminals, i.e. single element damage, double element damage, damage of double elements in the same bridge arm, high bus temperature from up to bottom respectively as well as the common terminal for above four faults. Terminals 6-13 are column line terminals of the elements connected in the matrix mode and the binding post 14 is the temperature column terminal.
There are only 4 terminals in the middle row, i.e. two 220V AC power supply terminals in the top and 485A and 485B communication terminals in the bottom.
In 13 terminals with an installation mark in the right row, 12 terminals from up to bottom are row line terminals of the elements connected in the matrix mode, with 1st row at the top (first under the installation mark) and 12th raw at the bottom, i.e. row 1, row 2, row 3...row 12. The terminal KIN at the bottom (13th) is the address setting allowed terminal.
Ⅵ. Connection
The terminal connection diagram and explanatory note are pasted on both sides and at the back of the enclosure. Make sure to connect correctly according to the note in the connection.
Special notes:
1. 220V AC power supply must be connected in the top two terminals of the binding posts in the middle row. If it is connected to any other two terminals, the detector will be burnt.
2. Do not try to take the circuit board out from the enclosure and be sure to pay attention to the installation mark when reloading if taking out; otherwise, wrong wiring may burn the detector.
3. The detector burnt due to wrong connection of 220V power supply does not enjoy warranty.
