Abstract
The utility model provides a low voltage drawer cabinet live-line operation switch misoperation prevention interlocking device. A drawer position interlocking mechanism is provided with a micro-stroke switch, and a contact of the micro-stroke switch is connected with a switching on/off circuit of a switch electric operation structure. The drawer position interlocking mechanism is provided with the micro-stroke switch, and the contact of the micro-stroke switch is connected with the switching on/off circuit of the switch electric operation structure. When the drawer is disposed in the switch cabinet, an operation handle of the drawer position interlocking mechanism can be switched from a drawing position to an experiment position, a mechanism rotary shaft can be used to drive the motion of the micro-stroke switch, and a normally-opened contact of the micro-stroke switch can be switched on, the switching off circuit of the electric operation mechanism is switched on, and the switching on circuit is switched off, and the electric operation cannot be switched on by a switching on button via external operators. By using the low voltage drawer cabinet live-line operation switch misoperation prevention interlocking device, the switching on of the switch caused by the manual misoperation of the drawer panel switching on button can be prevented during the experiment, the danger can be eliminated, and the safety can be guaranteed.
Description
Technical field
The utility model relates to the charged behaviour's switch of a kind of low-voltage drawer cabinet and prevents the misoperation interlock, particularly a kind of interlock that prevents the charged misoperation of 0.4KV low-voltage drawer cabinet.
Background technology
Along with the grow with each passing day application of electrical technology in power supplying and distributing equipment, very high to security requirement, a kind ofly simply, safe and reliable prevent that the interlock of charged misoperation from being necessary so design.0.4KV low-voltage drawer cabinet is present factory distribution power distribution cabinet commonly used, switch configuration motor-operating mechanism in certain customers' requirement drawer because drawout cubicle has " extraction, experiment, combined floodgate " three positions, is to consider handling safety, does not allow a deciliter switch in the experiment position.
The utility model content
The purpose of this utility model is a kind of simple, safe and reliable electric interlocking installation that prevents from testing the charged misoperation motor-operating mechanism in position of design.
The utility model adopts following technical scheme:
The charged behaviour's switch of low-voltage drawer cabinet prevents the misoperation interlock, comprises inlet wire lead, inlet wire plug-in unit, moulds the shell switch, switch motor-operating mechanism, divide-shut brake indicator light, divide-shut brake button, drawer positions interlocking device, secondary connect lead, feed wire and feed plug-in unit; It is characterized in that: in drawer positions interlocking device micro limit switch is installed, switch electric operating structure divide-shut brake loop is inserted in the micro limit switch contact.
In drawer positions interlocking device micro limit switch is installed, switch electric operating structure divide-shut brake loop is inserted in the micro limit switch contact, after drawer drops into switch cubicle, when operating grip goes to the experiment position from extracting the position out in the drawer positions interlocking device, mechanism's rotating shaft drives the micro limit switch action, micro limit switch normally opened contact closure, electronic behaviour does mechanism's sub-gate circuit conducting, closing circuit disconnects, the outside manually can't be by the closed electricity behaviour of switch knob, thereby when having avoided experiment, the people closes a floodgate for misoperation drawer panel switch knob causes switch, eliminate danger, guaranteed safety.
Description of drawings
Fig. 1 is the utility model mounting structure schematic diagram;
Fig. 2 is the utility model electrical schematic diagram;
Wherein, among Fig. 1: 1 inlet wire lead, 2 is moulded shell switch, 3 switch motor-operating mechanisms, 4 divide-shut brake indicator lights, 5 divide-shut brake buttons, 6 drawer positions interlocking devices, 7 micro limit switch, 8 secondaries connect lead, 9 feed wires, 10 feed plug-in units, 11 inlet wire plug-in units;
Among Fig. 2: QF: mould the shell switch, M: motor-operating mechanism, S: micro limit switch, SB: switch knob, HG: separating brake indicator light, SBT: opening button, HR: combined floodgate indicator light.
Embodiment
Embodiment 1: the charged behaviour's switch of low-voltage drawer cabinet prevents the misoperation interlock, comprises inlet wire lead, inlet wire plug-in unit, moulds the shell switch, switch motor-operating mechanism, divide-shut brake indicator light, divide-shut brake button, drawer positions interlocking device, secondary connect lead, feed wire and feed plug-in unit; In drawer positions interlocking device micro limit switch is installed, switch electric operating structure divide-shut brake loop is inserted in the micro limit switch contact.Switch electric operating structure divide-shut brake loop is inserted in the micro limit switch contact, when drawer is in the experiment position, mechanism's rotating shaft drives the micro limit switch action, micro limit switch normally opened contact closure, the conducting of electricity behaviour sub-gate circuit, closing circuit disconnects, and the outside manually can't be by the closed electricity behaviour of switch knob, eliminate danger, guaranteed safety.
