Abstract
The utility model relates to an error operation prevention device for electric switch cabinets, which comprises a transformer, a rectifier and a horn. The utility model is characterized in that a travel switch of an electric cabinet door is connected with an infrared proximity switch and a flashing relay, and a primary pole of the transformer is connected with the travel switch of an electric cabinet door, the infrared proximity switch and the flashing relay; both ends of a plurality of parallel speech generators are connected with a positive pole and a negative pole of the rectifier, the travel switch or an auxiliary contact of a breaker is connected between every two speech generators, the travel switch is connected in series with a contact of the travel switch of the cabinet door and a contact of the flashing relay, and the auxiliary contact of the breaker is connected with the contact of the flashing relay by the travel switch. The utility model has the advantages of safe and reliable use and simple structure.
Description
The utility model belongs to a kind of cabinet anti-misoperation apparatus.
It is anti-error that the anti-misoperation apparatus that present various high and low pressure cabinet is adopted is mechanical type, cooperate electrical interlock, it has the following disadvantages and defective: 1, the current running status of regulator cubicle is not had detection, operating personnel's this regulator cubicle (switch) state of living in directly perceived before operation has the possibility that misoperation takes place.2, when the misoperation of operating personnel's good will, since moveable part in cabinet when mobile resistance bigger, must enforce (perhaps extensible part is with shaking into mechanism's operation), the mechanical anti-misoperation device just may be malfunctioning, thereby cause great casualties, equipment scrapping accident.
The purpose of this utility model provides a kind of anti-misoperation apparatus of novel cabinet, and is safe and reliable, simple in structure.
The purpose of this utility model is achieved in that it comprises transformer, rectifier, loudspeaker, and its technical scheme main points are: regulator cubicle door travel switch connects infrared ray near switch and flashing relay; The elementary connection regulator cubicle travel switch of transformer, infrared ray are near switch and flashing relay; A plurality of speech synthesizer two ends arranged side by side connect the both positive and negative polarity of rectifier, connect travel switch or circuit breaker auxiliary contact between per two speech synthesizers, travel switch serial connection cabinet door travel switch contact and flashing relay contact, the circuit breaker auxiliary contact connects the flashing relay contact altogether by travel switch.
The utility model has the advantages that; Safe and reliable, avoid accident to take place, simple in structure.
Provide specific embodiment below in conjunction with accompanying drawing.
Fig. 1 is the utility model structural representation.
See Fig. 1, concrete structure is as follows: relay Photoelectric infrared switch K1 adopts alternating current 220V voltage, and its end connects flashing relay J2 and transformer B primary side, and the other end connects cabinet door travel switch J1; The two ends of a plurality of speech synthesizer I1-I6 arranged side by side are connected the both positive and negative polarity of rectifier ZL, wherein connect travel switch J3 between speech synthesizer I1 and the I2, travel switch J3 connects the normally-closed contact J1-2 of the cabinet door travel switch J1 that is connected in series and the normally opened contact J2-1 of flashing relay J2; Connect seed road device auxiliary contact K2 between speech synthesizer I3 and the I4; Connect killer switch auxiliary contact K3 between speech synthesizer I5 and the I6; By travel switch J4, J5 meets the normally opened contact J2-2 of flashing relay altogether respectively for killer switch auxiliary contact K2 and K3.Loudspeaker Y is connected with each speech synthesizer.
Operation principle: when the switch cubicle door is closed, regulator cubicle door travel switch J1 closure, when human body during near switch cubicle, infrared ray is connected near K switch 1, and flashing relay contact J1-1 flashes connection, sends two kinds of voice suggestions respectively:
A: when in the cabinet door car being arranged, travel switch J3 connects speech synthesizer I1, sends the voice suggestion of " danger, separating brake back pullout (BPO), follow procedure operation " by loudspeaker.
B: when in the cabinet during no car, travel switch J2 connects speech synthesizer I2, sends the voice suggestion of " close behind the door, divide the ground connection switch, the follow procedure operation " by loudspeaker.
After the cabinet door was opened, infrared ray quit work because of cabinet door travel switch J1 disconnects near K switch 1, and contact J1-1, J1-3 junction closure, the charged again work of flashing relay J2, flashing relay J2-2 connects.This moment also may be in the service position because car may be in test position in the cabinet.Voice system will send following voice suggestion:
C: car travel switch J4 when test position connects, and when switch closed a floodgate, circuit breaker auxiliary contact K2 connected speech synthesizer I3, sent the prompting of " test position is closed a floodgate, push-and-pull behind the separating brake ".
D: car is in test position, but during separating brake, circuit breaker auxiliary contact K2 connects speech synthesizer I4, the prompting of sending " test position, separating brake can be operated ".
E: car is when the service position, and travel switch J5 connects, when switch closes a floodgate, circuit breaker auxiliary contact K3 connection speech synthesizer I5, send following warning: " close a floodgate in the service position, not Cao Zuo, close the door soon " prompting.
F: car is in the service position, but during separating brake, circuit breaker auxiliary contact K3 connects speech synthesizer I6, sends following prompting: " service position is separating brake, can spur, and closes a floodgate and closes the door earlier ".
