Abstract
The utility model relates to a combination-type electric motor control device which mainly solves the problems existing in the prior control technology of the electric motor of the oilfield oil extractor of repeated setting, more fault points, high failure rate and complex maintenance. The combination-type electric motor control device is characterized in that a controller (11) which is arranged in a casing and connected between an electric motor (1) and a power supply (12) comprises a protector (2) and an automatic air switch (3); and a circuit lead connected with the electric motor (1) penetrates through a current sensor (5) in the protector (2), and breaker tripping coils (8) and (9) in the protector (2) are respectively connected with the automatic air switch (3). The device has the advantages of strong protection function, simple structure, convenient use and no need of maintenance.
Description
Technical field:
The utility model relates to the used a kind of control device in oil field, belongs to the used combination motor control device of a kind of oil-field oil pumper.
Background technology:
In oil recovery field, oil field, oil pumper generally adopts motor as power.And be applied in oil-field oil pumper Electric Machine Control fault 70% partly all at contactor and button part.And the existing widely used Electric Machine Control part of oil-field oil pumper, its major loop is power supply, air switch, contactor and motor; Control loop is power supply, button, protector and contactor coil, wherein the break-make of air switch control main circuit power; The break-make of contactor control main circuit power; The break-make of button control control loop power supply; Protector detects the major loop operating current, control A.C. contactor, and then control main circuit power break-make.
Above setting exists A.C. contactor and air switch is provided with repetition, and A.C. contactor is when work, the phenomenon that is prone to the contact adhesion or breaks not open, have the loosening phenomenon such as thermal oxidation that caused of the many or contact of contact, failure rate is than higher, and maintenance is complicated.
The utility model content:
In order to solve the failure rate height that exists in the existing oil-field oil pumper Motor Control technology; the maintenance complicated problems; the combination motor control device that the utility model provides, this device have defencive function advantage strong, simple in structure, easy to use, that need not keep in repair.
The purpose of this utility model is achieved by the following technical solution: this device comprises motor, power supply, connect a controller that places in the housing between motor, the power supply, and controller is made up of protector and air automatic switch; The circuit lead that is connected in motor passes the interior current sensor of protector, and two circuit breaker tripping coils in the protector are connected to two contacts of air automatic switch.
The utlity model has following effect: owing to directly connected the controller that places housing interior between this device motor, power supply, make the simple in structure of this device, contact has reduced, and components and parts have reduced, and defencive function has strengthened on the contrary; Have easy to use, maintenance free advantage, be suitable for uses such as oil field, agricultural production and field, mine.
Description of drawings:
Accompanying drawing 1 is a circuit diagram of the present utility model.
In the accompanying drawing: the 1-motor, the 2-protector, the 3-air switch, the 4-temperature relay, the 5-current sensor, 6-changes road switching amplifier, 7-single-chip microcomputer, 8-circuit breaker tripping coil, 9-circuit breaker tripping coil, 10-relay-operated controller, 11-controller, 12-power supply.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, this device comprises motor 1, power supply 12, connects a controller 11 between motor 1, the power supply 12, and this controller 11 places in the housing and is closed, and makes that the contact of this device is few, the phenomenon that is not prone to the contact adhesion or breaks not open; And controller 11 is made up of protector 2 and air automatic switch 3, and the circuit lead that is connected in motor 1 passes the current sensor 5 in the protector 2, makes current sensor 5 obtain the signal of motor 1; And the circuit breaker tripping coil (8,9) in the protector 2 is connected to air automatic switch 3, can make air automatic switch 3 with the automatic disconnection of signal situation.
During concrete operations, when motor 1 is started working, when short circuit, phase shortage, overcurrent appear in main circuit, protector 2 actions, current sensor 5 is gathered motor 1 and is transmitted the current signal of coming, and through converter amplifier circuit 6, signal is amplified, single-chip microcomputer 7 carries out logic determines and protection is handled, signal is transferred to relay-operated controller 10, relay-operated controller 10 actions, circuit breaker tripping coil 8 gets electronic work, air switch 3 is disconnected, realize first class of protection motor 1; After circuit breaker tripping coil 8 gets electric three seconds, if air switch 3 does not still disconnect, illustrate that circuit breaker tripping coil 8 is unusual this moment, at this moment, single-chip microcomputer 7 carries out logic determines and protection is handled, and signal is transferred to relay-operated controller 10 once more, relay-operated controller 10 actions, at this moment circuit breaker tripping coil 9 must be electric, and air switch 3 is disconnected, and realizes the second class protection to motor; When protector 2 damages fully; when circuit breaker tripping coil 8 all can not get electronic the work with circuit breaker tripping coil 9; be embedded in the temperature relay 4 of motor 1 coil inside; when temperature rises to the numerical value of setting; circuit breaker tripping coil 9 gets electronic work at this moment; drive the mechanical part of air automatic switch 3; air switch 3 is disconnected; realization is to the three-level protective of motor 1; as seen the defencive function of this device has strengthened; and have easy to use, maintenance free advantage, be suitable for uses such as oil field, agricultural production and field, mine.
