Abstract
The utility model relates to a lightning protection and grounding carbon brush abrasion alarm system for a wind power generator, which comprises a carbon brush detecting probe normally-closed switch connected with a signal source. The carbon brush detecting probe normally-closed switch is connected with an I/O (input/output) module input port by the aid of a lead; an I/O module output port is connected with a data processing device by the aid of a lead; and the data processing device is connected with a remote terminal by the aid of wireless signals. The lightning protection and grounding carbon brush abrasion alarm system realizes unattended management by the aid of automatic monitoring for a carbon brush, decreases manual maintenance to the maximum extent, shortens high-altitude operation time, utilizes an existing carbon brush module to the maximum possible, and reduces replacement time. Stability of the system is improved, and maintenance cost is reduced. The lightning protection and grounding carbon brush abrasion alarm system is simple in structure, convenient in realization and fine in reliability.
Description
Technical field
The utility model relates to a kind of warning system, especially a kind of wind-driven generator lightning protection, ground connection carbon brush abrasion warning system.
Background technology
Wind-driven generator belongs to the high-altitude operational outfit, also want more than 80 meter apart from ground is minimum, and running environment is abominable, therefore safeguards quite difficulty.Lightning protection carbon brush, ground connection carbon brush are applied to two relative rotating partss of wind-driven generator, by carbon brush and axle class friction and conducting, thereby reach the purpose of earthing and lightning protection.Someone image with carbon brush than being the heart of blower fan protection safety chain, visible its residing status in the blower fan theft-resistant link chain.
Carbon brush belongs to easily-consumed products, and the carbon brush of longest-lived only can be with short two to three years, as its life-span of common carbon brush just shorter, this also depends on the surface quality that carbon brush is paid mill.Generally, carbon brush places in the cat head cabin, arranges the special messenger regularly it to be checked replacing.
The drawback of this maintenance mode mainly shows:
One, because need special messenger's periodic maintenance, increased maintenance cost, owing to all need to climb to tower tube top at every turn, certain potential safety hazard has been arranged simultaneously.
Two, manual maintenance is a regular process, and the carbon brush abrasive wear is full of at random, and in a maintenance period, a kind of may be that carbon brush is changed under unspent situation in advance, causes certain waste like this; Another kind may be exactly that the carbon brush abrasion totally and not are found, thereby jeopardizes the safety of blower fan even damage blower fan.
Three, some carbon brush is installed in device interior, may not see inner operating position under the situation of not opening equipment, can only be the parameter periodic replacement that provides according to accessory producer, and it is passive and inconvenient to bring to maintenance work.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, provide a kind of easy to operate, can guarantee that blower fan is long-term, stable, economy, the wind-driven generator lightning protection of safe operation, ground connection carbon brush abrasion warning system.
For achieving the above object, the utility model adopts following technical proposals:
A kind of wind-driven generator lightning protection, ground connection carbon brush abrasion warning system, comprise the carbon brush detection probe normally closed switch that links to each other with signal source, carbon brush detection probe normally closed switch links to each other with I/O module input mouth by lead, I/O module output port links to each other with data processing equipment by lead, and data processing equipment links to each other with remote terminal by wireless signal.
Described signal source is direct current 24V.
Described data processing equipment is PLC.
Described wireless signal is GSM.
The utility model is made up of PLC, I/O module, DC24V, abrasion detection contact four parts.At first, the 24V signal arrives the I/O module through carbon brush detection probe normally closed switch, by PLC the I/O port is detected then, and the I/O port should keep high level under the normal condition; When the carbon brush wearing and tearing exhausted, normally closed switch disconnected, and the I/O port becomes low level.It is which carbon brush needs that go wrong are changed that PLC can judge according to the I/O port address, and PLC sends to remote terminal with information by the GSM signal simultaneously, and the complete process monitoring.
When the utility model is used, guarantee that direct current 24V continues to keep; The connection of attention line when changing carbon brush; After receiving carbon brush to exhaust alarm signal, should change carbon brush at the appointed time.
The utility model has been realized unattended operation by the automatic monitoring to carbon brush, farthest reduces manual maintenance, shortens the work high above the ground time; The utilization of maximum possible has the carbon brush module now, reduces and changes number of times.Both improve the stability of system, reduced maintenance cost again.The utility model is simple in structure, and it is convenient to realize, good reliability.
Description of drawings
Fig. 1 is the utility model schematic diagram.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1, a kind of wind-driven generator lightning protection, ground connection carbon brush abrasion warning system, comprise the carbon brush detection probe normally closed switch that links to each other with the signal source of direct current 24V, carbon brush detection probe normally closed switch links to each other with I/O module input mouth by lead, I/O module output port links to each other with PLC by lead, and PLC links to each other with remote terminal by the gsm wireless signal.
The utility model is made up of PLC, I/O module, DC24V, abrasion detection contact four parts.At first, the 24V signal arrives the I/O module through carbon brush detection probe normally closed switch, by PLC the I/O port is detected then, and the I/O port should keep high level under the normal condition; When the carbon brush wearing and tearing exhausted, normally closed switch disconnected, and the I/O port becomes low level.It is which carbon brush needs that go wrong are changed that PLC can judge according to the I/O port address, and PLC sends to remote terminal with information by the GSM signal simultaneously, and the complete process monitoring.
