Full transcript

1. 0:10hi all
2. 0:11my name is mas batenkop from kaiser
3. 0:13power electronics and today we're taking
4. 0:15a look at this good old merlin sharing
5. 0:17master pact 16n1 it is a
6. 0:211600 amp circuit breaker
7. 0:24manually pumped also with a motor loader
8. 0:28so i think we're going to have some fun
9. 0:31with this and
10. 0:35make a quite a jump on the workbench
11. 0:38here when we try to
12. 0:39switch it on as you can see right when i
13. 0:42get it here it says
14. 0:43charts so the spring is right now
15. 0:46charged
16. 0:46and it is off so with the
17. 0:49under voltage control or under muscles
18. 0:52circuit
19. 0:53powered up we should be able to switch
20. 0:54it in by simply
21. 0:56pressing the on button so before getting
22. 0:59ahead of ourselves
23. 1:00we need some coffee
24. 1:04when i picked this up i was
25. 1:06unfortunately only on my bicycle
26. 1:08and it was a yeah chance do you want to
27. 1:10get it or do it not
28. 1:12so i had to bring it home on my bicycle
29. 1:14so yeah
30. 1:16that was quite a ride taking that home
31. 1:18two kilometers
32. 1:20so we're going to take it apart check
33. 1:23out
34. 1:23the design inside and then we're going
35. 1:26to see if it works
36. 1:27and then maybe in some future videos do
37. 1:29some actually
38. 1:30high voltage short circuit tests maybe
39. 1:33some high speed
40. 1:34video filming of it so yeah let's just
41. 1:36have some fun
42. 1:39whoa at the front page here we have the
43. 1:41product name we can also see it's tested
44. 1:43up to 1 000 volt ac
45. 1:45but normally 380 to 690 volt
46. 1:49ac so that at 1600 amps makes this up
47. 1:52around
48. 1:53one megawatt of switching capability
49. 1:56which is
50. 1:56insane manually charged as i said before
51. 2:00with this handle
52. 2:01we also have a short circuit curve
53. 2:04limiting
54. 2:04feature over here with three
55. 2:06potentiometers you can set the
56. 2:08different timings of the curve as it
57. 2:10should be switching out on
58. 2:12and you can also yeah reset that now
59. 2:15something that is rated
60. 2:16for 1600 amps also has to have some
61. 2:19pretty nice huge terminals
62. 2:23so what we have here is something like
63. 2:26eight centimeters times one so
64. 2:3180 square millimeter thick copper
65. 2:34terminals here at the back
66. 2:35three of them as it's a three-phased
67. 2:37unit the entire front here
68. 2:39can be taken off to reveal
69. 2:43the electronics and mechanics inside
70. 2:48as it is trout right now i do not want
71. 2:50to put my fingers into this whole
72. 2:52mechanism which is the
73. 2:54i don't even think it down here we can
74. 2:56see the charged
75. 2:57spring so let's take a look at that
76. 2:59afterwards but
77. 3:00all that we can see that over here the
78. 3:02charge handle we have a large
79. 3:04gear as it is a very hot loaded spring
80. 3:07we also have a small motor so this can
81. 3:10be motor charged
82. 3:11seems to have some water damage on the
83. 3:13pcb here hopefully that is
84. 3:16okay we have a terminal plug over here
85. 3:19that connects down to the
86. 3:21release spring or release mechanism and
87. 3:24also have a
88. 3:25under voltage mechanism so we have to
89. 3:28power the under voltage mechanism in
90. 3:30order
91. 3:31to switch it on and we can also remote
92. 3:34trigger it with this
93. 3:35release coil here wow
94. 3:38look at that spring
95. 3:42it is some 50 millimeters and in this
96. 3:45compressed
97. 3:46state it is down to some 60 millimeters
98. 3:50and i think it will extend
99. 3:53yeah well so maybe 10 10 12 centimeters
100. 3:58that this whole arm assembly here will
101. 4:01get all the way up
102. 4:02to around here so that is
103. 4:05a serious amount of kinetic energy
104. 4:07stored in that spring
105. 4:10at the top we have the three arc
106. 4:12chimneys and this is
107. 4:14simply a arc extinguisher
108. 4:17device which is just
109. 4:21a a lot of metal plates
110. 4:24to take the heat out of a switching arc
111. 4:27or
112. 4:27short circuit fault current here we're
113. 4:30looking straight down into the switching
114. 4:32chamber over here we have the moving arm
115. 4:35we can see it consists of one two three
116. 4:38four five six seven eight nine ten
117. 4:42parallel couple levers which have some
118. 4:45switching elements sitting down here and
119. 4:47we can also see the
120. 4:49output terminal directly over here
121. 4:51getting hit
122. 4:52but it does have a wear surface just
123. 4:56a 1 to 2 millimeter thick plate here
124. 4:59and that is seriously dented all these
125. 5:02black marks are dense
126. 5:03going into it from the switching element
127. 5:05over here
128. 5:06we can also see arc
129. 5:09seeing as we have rust forming here
130. 5:12that the metal itself has simply been
131. 5:14damaged by the
132. 5:16hot air when switching this in okay so i
133. 5:19have only hooked up the under voltage
134. 5:21release coil
135. 5:22i can switch that on here and with that
136. 5:24switch on to 230 volt ac we should be
137. 5:26able to
138. 5:27switch it in i did not hook up the motor
139. 5:31because that's rated for 380 volt ac so
140. 5:33i would have to get that from my
141. 5:35big plugs here so yeah let's try
142. 5:38to turn on the under voltage release
143. 5:41coil
144. 5:43something clicked something clicked
145. 5:50again
146. 5:52okay let's try once again this time i
147. 5:54have the answer voltage coil and also a
148. 5:56closing release coil hooked up so we
149. 5:58will switch it on first the under
150. 6:00voltage coil then close release
151. 6:02so let's see how that goes
152. 6:10it does make some clean sounds
153. 6:36okay so apparently we have this small
154. 6:38circuit here
155. 6:39with sets at time and this is the time
156. 6:41between we have to
157. 6:43engage the under voltage coil and the
158. 6:45release coil and then it automatically
159. 6:47tried to switch in
160. 6:48and then try to switch off again perhaps
161. 6:52internal fault missing main voltage i'm
162. 6:55not sure of that
163. 6:56it's very hard to find a manual for this
164. 6:58old unit here
165. 6:59so i actually am using some
166. 7:03newer manuals here for some much newer
167. 7:06products but seems to have the same
168. 7:09terminal designations so i could at
169. 7:11least get it to work
170. 7:13but i want to hear this without the ear
171. 7:16defenders on
172. 7:17so let's try that again
173. 7:21and well
174. 7:24[Laughter]
175. 7:29and nothing happens
176. 7:31[Music]
177. 7:34that might be because i have to charge
178. 7:36it again
179. 7:37so let's do that
180. 7:42ah
181. 7:50and just like that it's cranked and
182. 7:54charged again so let's try to turn it on
183. 7:57whoa
184. 7:59that is a serious kick
185. 8:04[Music]
186. 8:08this is awesome i'm going to do some
187. 8:10high-speed photography of this
188. 8:12where we tried to switch off four
189. 8:14kilojoules of capacitor
190. 8:15energy into something and then maybe do
191. 8:18some high-speed filming down into this
192. 8:19spark
193. 8:20arrestor area this is going to be
194. 8:22awesome so
195. 8:23until next time see ya
196. 8:30[Music]
197. 9:00you
