Description
Technical field:
The utility model relates to a kind of wind power generating set, particularly a kind of wind generating set yaw brake block excessive abrasion early warning protector.
Background technique:
In the process of the normal operation of wind power generating set; driftage brake disc in the yaw system is worn easily; the driftage brake disc by heavy wear after; dismounting is complicated and need return factory's replacing; cost is higher; simultaneously, also can cause wind power generating set to shut down, thereby influence the output of wind energy turbine set generated energy.The driftage brake disc is made up of driftage lock body, Yaw brake block and Yaw brake block three parts, and Yaw brake block belongs to wear parts.Because the yaw system of existing wind power generating set has only the yaw motor overload protection; there are not scheme or device about warning of Yaw brake block excessive abrasion and protection; the irony of Yaw brake block part will be to the wearing and tearing of damaging property of driftage brake disc after more serious wearing and tearing appear in Yaw brake block, cause yaw system especially brake system can't normally use.Process in the wind power generating set operation maintenance, in order to prevent the Yaw brake block excessive abrasion, the operation maintenance personnel need regularly to check by modes such as range estimation or manual measurements the wear extent of Yaw brake block, this artificial maintenance mode, consuming time, consumption power, Security are low, and accuracy is relatively poor.
Summary of the invention:
The purpose of this utility model provides a kind of wind generating set yaw brake block excessive abrasion early warning protector; can realize under unattended situation that the maximum that detects Yaw brake block automatically allows wear extent; and realize the malfunction alarm or the shutdown of wind power generating set with this; protection driftage brake system makes the operation maintenance personnel can change Yaw brake block timely.
In order to address the above problem; the utility model wind generating set yaw brake block excessive abrasion early warning protector is by limit switch; the auxiliary reclay coil; auxiliary reclay coil working power supply; signal power source; switching input module is formed; the limit switch of setting the wear extent critical value is by being bolted on the Yaw brake block lateral retaining plate; limit switch is connected with the auxiliary reclay coil; the auxiliary reclay coil is connected by the both positive and negative polarity of limit switch with auxiliary reclay coil working power supply, and the detection input point of switching input module is connected with the positive pole of described signal power source by the normally-closed contact of auxiliary reclay.
In the utility model device, limit switch comprises pull bar, the normally opened contact that spring is installed, and normally opened contact comprises movable contact and stationary contact, and movable contact is connected with described pull bar, and stationary contact is fixed on the insulating guide rail of pull bar.
In the utility model device, the pull bar of limit switch is shaped as " L " letter shapes.
In the utility model device, the normally opened contact of limit switch be a pair of more than.
This device makes application more flexible owing to adopted auxiliary reclay, and is reliable.By the protection of the utility model device, can effectively avoid the excessive abrasion of Yaw brake block, effectively protection driftage brake system.
Description of drawings:
Fig. 1 is the left side view of the utility model wind generating set yaw brake block excessive abrasion early warning protector and installation position thereof;
Fig. 2 is the installation position front view of the utility model wind generating set yaw brake block excessive abrasion early warning protector.
Fig. 3 is the schematic representation of limit switch in the utility model wind generating set yaw brake block excessive abrasion early warning protector.
Embodiment:
With reference to Fig. 1, the utility model device comprises limit switch 16, auxiliary reclay coil 4, auxiliary reclay normally-closed contact 5, auxiliary reclay coil working power cathode 1, auxiliary reclay coil working positive source 2, switching input module detectable voltage signals source positive pole 3, switching input module 6, lead 14 and lead 15.
With reference to Fig. 3, limit switch in this suitable model utility device comprises pull bar 20, the normally opened contact that spring is installed, normally opened contact comprises movable contact 18 and stationary contact 19, and movable contact 18 is connected with described pull bar 20, and stationary contact 19 is fixed on the insulating guide rail 13 of pull bar.
See figures.1.and.2, fixed limit switch 16 on the bolt 10 of the Yaw brake block lateral retaining plate 9 of driftage brake body 7, the pull bar 20 of limit switch 16 keeps closely being connected with Yaw brake block 11 by spring 12, the guide rail 13 of pull bar 20 is made of the ambroin material, the normally opened contact of limit switch is connected in auxiliary reclay coil 4 loops, the stationary contact 19 of normally opened contact is a metallic material, is fixed on the insulating guide rail 13.Be used to detect the limit switch 16 of Yaw brake block greatest wear amount critical value by pull bar 20 and Yaw brake block 11 realization interlocks, when Yaw brake block 11 wear extent increase after, because the oil hydraulic cylinder 21 in the driftage brake body 7 can be extrapolated with Yaw brake block 11, and the pull bar 20 of limit switch 16 can outwards stretch in company with Yaw brake block 11, after Yaw brake block 11 reaches greatest wear amount critical value, the movable contacts 18 that are connected with pull bar 20 in the limit switch 16 can with stationary contact 19 closures, connect auxiliary reclay coil 4 loops, realize the transformation from the wear extent to the electric potential signal.
When implementing; anodal 3 voltage signals of signal power source that will be used for detecting to switching input module 6 are connected to the input point of switching input module 6 by the normally-closed contact 5 of auxiliary reclay; make PLC cooperate the corresponding software logic control; after the corresponding input point voltage signal that is implemented in switching input module 6 is lost; blower fan is quoted fault or shutdown, thereby realizes early warning and protection.
The another kind of mode of execution of the utility model; the normally-closed contact 5 of auxiliary reclay is concatenated in the theft-resistant link chain loop in the blower fan control system; when Yaw brake block 11 wear extenies reach the maximum permissible velocity dividing value; make the auxiliary reclay action by limit switch 16; thereby disconnect the theft-resistant link chain loop; blower fan is shut down, also realize protective function.
With lead 14 and lead 15 respectively and receive on two normally opened contacts in all limit switches.To realize after arbitrary Yaw brake block 11 reaches the greatest wear critical value, can both realize protection by this device.
The utility model can also be applied to other blower fan types by the adjustment to the limit switch shape except using and the 750kW wind power generating set.
