Embodiment
(embodiment 1)
See Fig. 2, the present embodiment hold the fault protection Controlling System holding brake coil, comprise power supply end, field effect transistor Q, warning light C, brake coil R, main motor contactor KMM and dust sucting motor contactor KPSA; Wherein power supply end employing voltage rating is the DC power supply end of 26V; Namely main motor contactor KMM is contactor existing in the circuit control of the main motor of loom, dust sucting motor contactor KPSA is contactor existing in the circuit control of dust sucting motor, open under normal circumstances after loom, main motor starting after 1 to 2 second dust sucting motor will start. Warning light C is connected with the normally opened contact of main motor contactor KMM: warning light C can connect with a normally opened contact of main motor contactor KMM, or the two ends of warning light C connect two normally opened contacts of main motor contactor KMM respectively, adopt the latter in the present embodiment. Brake coil R is connected with the normally closed contact of dust sucting motor contactor KSPA: brake coil R can connect with a normally opened contact of dust sucting motor contactor KSPA, or the two ends of brake coil R connect two normally opened contacts of dust sucting motor contactor KSPA respectively, adopt the latter in the present embodiment. The circuit of the normally opened contact composition of warning light C and main motor contactor KMM is the first circuit, the circuit of the normally closed contact composition of brake coil R and dust sucting motor contactor KSPA is the 2nd circuit, first circuit and the 2nd circuit compose in parallel the 3rd shunt circuit, 3rd shunt circuit is connected power supply after connecting with field effect transistor Q, that is: one end of the 3rd shunt circuit is connected with the positive pole of power supply end, the other end is extremely connected with the D of field effect transistor Q, and the S pole of field effect transistor Q is connected with the negative pole of power supply end.The G pole of field effect transistor Q is connected with the governor circuit of loom, and when loom starts, governor circuit is to the G pole emission control electrical signal of field effect transistor Q, and then field effect transistor Q is equivalent to circuitry cuts, and when loom cuts out, field effect transistor Q is equivalent to circuit turn-on.
The fault protection Controlling System that the holding of the present embodiment holds brake coil is after loom starts, when there is not fault normal operation in field effect transistor Q, the energising of main motor starts, the normally opened contact of main motor contactor KMM turns into closed state, field effect transistor Q is equivalent to circuitry cuts, warning light C does not form path and does not work, and the normally closed contact of dust sucting motor contactor KSPA turns into disconnection state, and brake coil is trip condition; When field effect transistor Q occurs fault to burn, field effect transistor Q is equivalent to be in channel status always, then warning light C is energized and starts bright light of reporting to the police, owing to the normally closed contact of dust sucting motor contactor KSPA is in disconnection state, then brake coil is still trip condition, it is disengage that brake coil dish holds brake flange with holding, and effectively prevent brake coil dish and does not disengage and hold the brake flange friction generation combustion-supporting colorful clothes of high temperature with holding.
