Abstract
The utility model discloses an automatic alarm high-tension switch gear cabinet by misoperation, which belongs to the technical field of supply equipment. The utility model mainly solves the problems of the prior art that the high-voltage power arc discharge is generated in the high voltage switch cabinet by misoperation, causing accidents of short circuit and power cut, and the safety of equipment and people are jeopardized. The utility model is characterized in that the high voltage switch cabinet is additionally provided with a DC automatic control circuit and an AC automatic control circuit, each of which comprises a controlling switch, an auxiliary contact, a disconnecting switch, etc. When misoperation of power supply or power cut, alarm can be sent out automatically and the high voltage switch cabinet can be protected. The automatic alarm high-tension switch gear cabinet by misoperation is used for the security protection of the supply equipment.
Description
Can report to the police automatically when the utility model is a kind of misoperation, particularly can the automatic protection high-tension switch cabinet, it belongs to the power supply unit technical field, it is by isolating switch, oil circuit breaker, fuse, D.C. contactor, control switch is formed.
In the prior art, high-tension switch cabinet is not provided with misoperation automatic-alarm receiver structure.Its purpose is operator's procedure operation in accordance with regulations: closed isolating switch earlier, rotate control switch again, connect DC power supply, the D.C. contactor adhesive, the oil circuit breaker closure is sent power supply to motor, when cutting off the electricity supply to motor, operator's operation sequence with send power supply just the opposite.Its weak point is: the operator in case not in accordance with regulations operation sequence operation successively just produce the high voltage source arc discharge, cause serious short circuit power cut accident, breaking-up equipment jeopardizes operator's personal safety.
The purpose of this utility model be to avoid above-mentioned weak point of the prior art and a kind of operation sequence operation successively in accordance with regulations is provided, oil circuit breaker can not be closed when sending power supply; Isolating switch can not disconnect when cutting off the electricity supply, and can send strong audible alarm, signal lamp shows the misoperation alert operator, has avoided the arc discharge short circuit accident and has jeopardized personal safety, thereby guaranteed that high-tension switch cabinet moves safely and reliably, satisfied the production technology needs.
The utility model can reach by following measure: the auxiliary contact 2XK that sets up fuse 2RD, D.C. contactor HC, operating mechanism in high-tension switch cabinet
2, circuit breaker DL
2, control switch KK is in series, and is connected between the DC power supply KM, this is first loop 10 of this automatic control circuit; The auxiliary contact 2XK of fuse 1RD, auxiliary relay J, operating mechanism
1, control switch KK is in series and forms branch road 1; Auxiliary contact 1XK, the circuit breaker DL of device J, sensitive switch continue in the centre
1Be in series and form branch road 2; Siren 12, control button A are in series and form branch road 3; Siren 12, auxiliary relay J are in series and form branch road 4; Light word display board signal lamp XD, auxiliary relay J are in series and form branch road 5, and series arm 1,2,3,4,5 all is connected in parallel between the AC power, and this is second loop 11 of this automatic control circuit.First and second loop is by control switch KK, auxiliary contact 2XK
1, 2XK
2, alarm and protection high-tension switch cabinet automatically when circuit breaker DL constitutes power supply or outage misoperation.
The utility model has following advantage compared to existing technology:
1, sets up automatic alarm and protection high-tension switch cabinet, can guarantee to power safely and reliably or cut off the power supply;
In case when power supply was sent in 2 misoperations, oil circuit breaker can not be closed; When cutting off the electricity supply, isolating switch can not disconnect, and sends strong audible alarm, and signal lamp shows the misoperation alert operator, avoids the arc discharge short circuit accident, guarantees personal safety.
As follows to description of drawings:
Fig. 1 is a kind of DC power supply automatically controlled circuit diagram of the present utility model.
Fig. 2 is a kind of AC power automatically controlled circuit diagram that mates with Fig. 1.
Symbol among the figure and numeral: XD is a light word display board signal lamp, and 1XK is the contact of sensitive switch, DL
1And DL
2Be circuit breaker, 2XK
1And 2XK
2Be the auxiliary contact of isolator operating mechanism, J is an auxiliary relay, and 12 is siren, HC is a D.C. contactor, and 1RD and 2RD are fuse, and KK is a control switch, A is a control button, and 1,2,3,4,5 respectively is series arm, and 10 and 11 is first loop and second loop of automatic control circuit.
Fig. 1 and Fig. 2 are the automatic control circuits of high-tension switch cabinet, and it is a kind of embodiment.Its proper operation power supply program is: the closed isolating switch of elder generation, rotate control switch KK again, and connect DC power supply, DL
2Be normally closed circuit breaker, 2K
2Be normally-closed contact, D.C. contactor HC gets the closed oil circuit breaker in electric back, send power supply to motor.Misoperation power supply protection program: the KK closure, when disconnecting because of isolating switch, the auxiliary contact 2XK of its operating mechanism
1Closure, 2XK
2Disconnect, H0 disconnects, and oil circuit breaker can not be closed, and J gets electric, and its auxiliary contact closure is connected AC power, and 12 get the electric strong sound that sends, and XD is bright.Misoperation power-off protection program: when misoperation is cut off the electricity supply, connect 1XK by manipulator body plan, auxiliary relay J gets electric adhesive, and 12 get the electric strong sound that sends, and XD is bright.
This automatic control circuit can be applied to the high-tension switch cabinet of 6000 volts or 10000 volts.
