Abstract
The utility model relates to a wire outlet device of a position sensor of an SRM, belonging the technical field of SRMs. The wire outlet device comprises a sensor cover (1) and an extension pipe (2); and is characterized in that the sensor cover (1) is provided with a threaded hole (3), and the extension pipe (2) is fixed in the threaded hole (3). Compared with the prior art, the wire outlet device has the advantages that a) a leading-out wire of the position sensor can be connected needless of dismounting a fan housing, and onsite installation is simplified; b) due to the fact that the fan housing is not required to be dismounted in the using process, the space for motor assembly is saved; c) a plug is led out of the fan housing, so that the plug can be conveniently detected and maintained, and position errors caused by connection looseness are reduced; and d) and connecting wires of the position sensor can be conveniently maintained onsite, and fault elimination can be conveniently implemented.
Description
Technical field
A kind of switched reluctance machines position transducer outgoing line device, belongs to switched reluctance machines (SRM) technical field.
Background technology
Switched reluctance machines is stator, rotor double-salient-pole variable reluctance motor, and stator, rotor form by silicon steel plate stacking, are wound with concentrated winding in stator poles, on rotor both without winding also without permanent magnet.This motor can be designed to multiple different phase table structure, and the number of poles of rotor also can have multiple different collocation.That this motor has is simple in structure, dependable performance, starting current are little, and starting moment is large, speed-regulating range width and efficiency advantages of higher.
For the operation of gauge tap reluctance motor, controller need to be processed the positional information of rotor, and this information can detect collection by position transducer, changes position signalling into electric impulse signal and is sent to controller.Position transducer need be arranged in motor, carrys out the transmission of settling signal by position signalling connecting line.
Position signalling line socket is arranged on to the outlet method of sensor wrap outer wall, there is assembling simple, low cost and other advantages, but while installing and using at the scene, fan housing dismounting just can must be carried out to the dismounting of plug, complex operation.For some occasions, fan housing and equipment room gap are very little, cannot dismantle fan housing, motor must be removed and the position line could be removed.For heavy-duty motor, because fan housing is very heavy, the on-the-spot dismounting position line is more difficult.And safeguard and easily occur becoming flexible because of inconvenience, cause position signal acquisition mistake, affect the normal operation of motor.
Summary of the invention
The technical problems to be solved in the utility model is, overcomes the problem that prior art exists, and needn't dismantle connection work and maintenance maintenance switched reluctance machines position transducer outgoing line device easily that fan housing can completing place sensor extension line.
The utility model solves the technical scheme that its technical matters adopts: this switched reluctance machines position transducer outgoing line device, comprise sensor wrap and extension, and it is characterized in that: in sensor wrap, be designed with a hole, extension is fixed in a hole.The effect in silk hole is for securing elongated pipe.
Described extension one end is designed with socket fixed station, and the other end of extension is designed with external thread, and silk is designed with internal thread in hole, and extension is threaded in a hole.The effect of extension is to draw wire.
Described extension one end fixed socket diameter is greater than extension diameter, and four screw fixed orifices are set on socket fixed station.
The length of described extension is according to motor center height setting, not isometric.
The beneficial effect that compared with prior art switched reluctance machines position transducer outgoing line device of the present utility model has is: solved existing switched reluctance machines because position transducer connecting line need to draw and be connected to control loop from motor internal, cause using the on-the-spot connection work that fan housing must be removed to ability completing place sensor extension line, and be not easy to check because connector is positioned at fan housing, increased because of problems such as the loosening positional faults occurring.Have:
A. needn't dismantle fan housing, just can carry out the connection work of position transducer extension line, simplify on-the-spot installation steps;
B. because of in use procedure, do not need to dismantle fan housing, saved motor assembling and used space;
C. plug is drawn fan housing, conveniently it is checked and is safeguarded, reduces because connecting the loosening positional fault occurring.And be convenient to field maintemance position transducer connecting line and troubleshooting effort thereof.
Accompanying drawing explanation
Fig. 1 is switched reluctance machines position transducer outgoing line device structural representation.
Fig. 2 is sensor wrap schematic diagram.
Fig. 3 is extension schematic diagram.
Wherein: 1, sensor wrap 2, extension 3, silk hole.
Embodiment
Fig. 1-3rd, the most preferred embodiment of the utility model switched reluctance machines position transducer outgoing line device, below in conjunction with accompanying drawing, 1-3 is described further the utility model.
As Figure 1-3: this switched reluctance machines position transducer outgoing line device, formed by sensor wrap 1, extension 2 and silk hole 3, can be according to the outlet angle of position transducer, in sensor wrap 1, open a hole 3, silk is provided with internal thread in hole 3, outside one end of extension 2, be provided with external thread, extension 2 is fixed in a hole 3 by screw thread.The other end of extension 2 need be designed with socket and install with four silk holes.For the plug of power supply or the installation of socket, realize connector.
As shown in Figure 3: the length of extension 2 is not isometric, the length of extension 2 can be determined according to the space between sensor wrap 1 and fan housing.Concrete size need design according to different motors.
The installation steps of this switched reluctance machines position transducer outgoing line device are as follows:
A, extension 2 is arranged in sensor wrap 1, determines after height, nut is screwed, complete the steady job of extension 2;
B, by the motor internal position line through install extension 2, socket is fixed on extension 2, the other end is plugged on location plate;
C, by plug by the rubber plug on fan housing, screw firmly with socket.
The above, it is only preferred embodiment of the present utility model, be not the restriction of the utility model being made to other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not depart from, any simple modification, equivalent variations and the remodeling above embodiment done according to technical spirit of the present utility model, still belong to the protection domain of technical solutions of the utility model.
