Abstract

Provided is a fire resisting shutter controller with an automatic phase sequence adjusting function. A phase sequence adjusting circuit is respectively connected with a phase sequence detecting circuit and a motor and composed of five controllable switches including a switch S1, a switch S2, a switch S3, a switch S4 and a switch S5, wherein the switch S1, the switch S2 and the switch S3 are power supplying switches, and the switch S4 and the switch S5 are phase adjusting switches. The switch S1, the switch S2 and the switch S3 are connected with the motor, the switch S4 and the switch S5 are respectively connected with the switch S2 and the switch S3 in serial mode, and a three-phase power source is connected with the switch S1, the switch S4 and the switch S5. The fire resisting shutter controller with the automatic phase sequence adjusting function has the advantages of being capable of automatically adjusting the phase sequence of a circuit, ensuring that the motor is supplied with power after phase adjusting is finished and the rotating direction of the motor is unchangeable, protecting the motor, and being simple in structure of the circuit and convenient to manufacture.

Description

The band phase sequence is adjusted the fire curtain controller of function automatically

Technical field

The utility model relates to a kind of fire curtain controller, relates in particular to a kind of fire curtain controller of adjusting function with phase sequence automatically.

Background technology

Fire curtain is a kind ofly when fire takes place, can effectively cut off burning things which may cause a fire disaster, prevents a kind of fire product of fire spread, and it is widely used in the fire separation of large tracts of land buildings such as megastore, supermarket, exhibition center, underground garage.Can control the fire curtain motor action automatically when taking place fire curtain is put down the partition burning things which may cause a fire disaster, just must be equipped with the fire curtain controller for the realization fire.The main drive disk assembly of fire curtain is exactly roller shutter motor (hereinafter to be referred as a motor); The working power of motor generally adopts and exchanges 380V; In case the power phase of access motor changes and will cause the rotation direction of motor to change, thereby causes enormous economic loss, take place for avoiding this situation; Circuit of testing the phase sequence has all installed in present domestic fire curtain controller manufacturer in controller; When inserting the phase sequence mistake of power supply, stop the rotation of motor, this kind method has been avoided the problem of the counter-rotating of motor from an angle, but puts to no little inconvenience in actual use.

Method described in the patent ZL 200620098254.2 has realized that phase sequence adjusts function automatically; Its operating principle is that circuit of testing the phase sequence connects three phase mains; The adjustment circuit connects three phase mains and motor, and testing circuit detects power supply earlier and inserts whether phase sequence is this machine operation phase sequence, as not being; Then switch phasing switch S4, S5, system default is that the phase sequence adjustment finishes.

Summary of the invention

The purpose of the utility model has been to provide a kind of fire curtain controller of adjusting function with phase sequence automatically; Its operating principle is that phase sequence adjustment circuit connects three phase mains; Connect circuit of testing the phase sequence and motor again; Whether testing circuit earlier detects default conditions is this machine operation phase sequence, as not being, then switching phasing switch S4, S5 and carries out phase sequence more again and detect; Can guarantee to open S1, S2, S3 power switch starter motor again after the phase sequence adjustment correctly, the phase sequence that the method described in the patent ZL 200620098254.2 of comparing can avoid factors such as S4, S5 fault to cause is switched unsuccessful.

The utility model is realized like this; It comprises phase sequence adjustment circuit, circuit of testing the phase sequence, motor; It is characterized in that phase sequence adjustment circuit connects circuit of testing the phase sequence and motor respectively, phase sequence adjustment electric routing switch S1, S2, S3, S4, five gate-controlled switches of S5 are formed, and wherein switch S 1, S2, S3 are to electric switch; Switch S 4, S5 are phasing switch; Switch S 1, S2, S3 connect motor, switch S 4 and S5 be connected in series respectively switch S 2, S3, and the three-phase electricity power supply connects switch S 1, S4, S5.

The technique effect of the utility model is: ability automatic circuit phase sequence, and guarantee to give electricity to motor again after the phase modulation success, guaranteeing the constant and protection motor of rotation direction of motor, circuit structure is simple, and is easily manufactured.

Description of drawings

Fig. 1 is the fundamental diagram of the utility model.

Fig. 2 is the circuit diagram of the utility model.

Power supply 2, phase sequence adjustment circuit 3, circuit of testing the phase sequence 4, motor in the drawings, 1.

The specific embodiment

Like Fig. 1, shown in Figure 2, the utility model realizes that like this phase sequence adjustment circuit 2 connects circuit of testing the phase sequence 3 and motor 4 respectively; Phase sequence adjustment circuit 2 is made up of switch S 1, S2, S3, S4, five gate-controlled switches of S5; Wherein switch S 1, S2, S3 are that switch S 4, S5 are phasing switch to electric switch, and switch S 1, S2, S3 connect motor 4; Switch S 4 and S5 be connected in series respectively switch S 2, S3, three-phase electricity power supply 1 connects switch S 1, S4, S5.Whether testing circuit detects default conditions earlier is these motor 4 work phase sequences, in this way, then directly opens S1, S2, S3 power switch starter motor; As be not, then to switch phasing switch S4, S5 and carry out the phase sequence detection more again, the method can be guaranteed to open S1, S2, S3 power switch starter motor 4 again after the phase sequence adjustment correctly.
