Abstract
The utility model relates to a three position sigual's of feedback exhaust smoke control circuit, including the drawer cabinet body, set up in the internal exhaust smoke of drawer cabinet, set up the drawer control circuit on exhaust smoke the moving contact, set up drawer control circuit static contact on the drawer cabinet body, normally closed contact travel switch, with the quiet contact connection's of drawer control circuit signal acquisition components and parts, travel switch set up in drawer cabinet is internal, with drawer control circuit static contact and signal acquisition components and parts connecting wire are connected, with the signal acquisition components and parts form parallelly connectedly, the installation is used for breaking off travel switch normally closed contact's the piece that hits on the drawer curb plate. The utility model discloses can provide exhaust smoke to the remote control platform keeps apart promptly in three position, tests and hookup location state information.
Description
Technical field
The utility model relates to low-voltage drawer cabinet, specifically discloses a kind of control loop feeding back drawer unit three position singal.
Background technology
In low-voltage drawer cabinet, drawer has three location statuss: isolation, test and link position.At present, client can collect drawer two positions (test and link position) information by control loop.When drawer is in test and link position, when control loop conducting, remote control table can collect drawer status data (as shown in Figure 2); And when drawer is in isolated location, i.e., under the situation of control loop not conducting, in remote control table, feedack is inaccurate.User also just can not fully understand drawer plug situation.
Utility model content
Goal of the invention of the present utility model is: provide a kind of drawer unit can be provided namely to isolate three positions to remote control table for overcoming the above problems, test and the control loop of link position state information.
The technical scheme that the utility model adopts is such:
A kind of control loop feeding back drawer unit three position singal, comprise drawout cubicle cabinet, the travel switch of the moving contact of the drawer unit be arranged in drawout cubicle cabinet, the drawer control loop be arranged on drawer unit, the drawer control loop fixed contact be arranged on drawout cubicle cabinet, normally-closed contact, the signals collecting components and parts that are connected with drawer control loop fixed contact, described travel switch is arranged in described drawout cubicle cabinet, be connected with described drawer control loop fixed contact and signals collecting components and parts connecting line, formed in parallel with described signals collecting components and parts; Drawer side is installed and hits sheet for what disconnect travel switch normally-closed contact.
In sum, owing to adopting technique scheme, the beneficial effects of the utility model are:
The utility model can provide drawer unit namely to isolate three positions, test and link position state information to remote control table, contributes to user and fullys understand drawer plug situation.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is prior art structure chart.
Mark in figure: 1, drawout cubicle cabinet; 2, drawer unit; 3, the moving contact of drawer control loop; 4, drawer control loop fixed contact; 5, travel switch; 6 signals collecting components and parts.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of control loop feeding back drawer unit three position singal, comprise drawout cubicle cabinet 1, be arranged at the drawer unit 2 in drawout cubicle cabinet 1, be arranged at the moving contact 3 of the drawer control loop on drawer unit 2, be arranged at the drawer control loop fixed contact 4 on drawout cubicle cabinet 1, the travel switch 5 of normally-closed contact, the signals collecting components and parts 6 be connected with drawer control loop fixed contact 4, described travel switch 5 is arranged in described drawout cubicle cabinet 1, be connected with described drawer control loop fixed contact 4 and signals collecting components and parts 6 connecting line, formed in parallel with described signals collecting components and parts 6, drawer side is installed and hits sheet for what disconnect travel switch 5 normally-closed contact.
The travel switch 4 of normally-closed contact is arranged in drawout cubicle cabinet 1, on the framework specifically near the fixed contact 4 of control loop.
In drawer unit 2 control loop moving contact 3 near, specifically outside drawer side, the position corresponding with travel switch 5 is installed one and is hit sheet.
Operation principle: (in figure, the direction of arrow is drawer unit direction of insertion)
Before the dynamic/static contact 3,4 of control loop contacts, namely when drawer is in isolated location, hits sheet and do not contact with travel switch 5, the normally-closed contact of travel switch 5 closes, now system is by loop, normally-closed contact travel switch 5 place, is gone out by the Signal transmissions of drawer in isolated location.
When the dynamic/static contact 3,4 of control loop is connected, namely the certain position of sheet bruising to travel switch 5 is hit, now the normally-closed contact of travel switch 5 disconnects and (hits the contact of sheet bruising travel switch 5 connecting rod driving switch, closed contact is caused to disconnect), now system passes through control loop, the test of drawer place or link position status signal are fed back to signal collecting element, realizes uploading of drawer test and link position information.
Above-described specific embodiment, further describes the purpose of this utility model, technical scheme and beneficial effect, and institute it should be understood that and the foregoing is only specific embodiment of the utility model, is not limited to the utility model.
Claims (1)
1. one kind is fed back the control loop of drawer unit three position singal, comprise drawout cubicle cabinet, be arranged at the drawer unit in drawout cubicle cabinet, be arranged at the moving contact of the drawer control loop on drawer unit, be arranged at the drawer control loop fixed contact on drawout cubicle cabinet, the travel switch of normally-closed contact, the signals collecting components and parts be connected with drawer control loop fixed contact, it is characterized in that: described travel switch is arranged in described drawout cubicle cabinet, be connected with described drawer control loop fixed contact and signals collecting components and parts connecting line, formed in parallel with described signals collecting components and parts, drawer side is installed and hits sheet for what disconnect travel switch normally-closed contact.
