Abstract
The diesel generating set anti-joy ride device and method of the present invention; one bypass resistance cabinet and a failure monitoring system are set; the bypass resistance cabinet is by protecting contactor and load circuit main circuit breaker and being connected in diesel generating set output terminal; the status signal of main disconnected device is sent into the failure monitoring system, the state of the output control protection contactor of the failure monitoring system.When main circuit breaker protectiveness or it is fault sudden shut off when; bypass resistance cabinet accesses circuit at once; it can be effectively prevented from the generation of the high rotating speed runaway accident of diesel engine; to the reaction time that unit control system and operating personnel are more abundant; the accident risk for operating bring in a hurry is reduced, unit is enable to complete to shut down according to normal procedure.
Description
Technical field
The present invention relates to a kind of diesel generating set anti-joy ride device and control methods, belong to diesel generation technical field.
Background technology
Diesel generating set in the process of running, for some reason rotating speed suddenly significantly acutely open rising, this
Kind phenomenon is referred to as driving.It, may be to diesel engine once generation driving, piston and cylinder can be subject to different degrees of wear damage
Destructive destruction is caused even to disintegrate.The reason for causing diesel generating set driving is not quite similar, wherein most commonly seen one
Kind be load circuit electric fault cause major loop contactor protectiveness or it is fault sudden shut off, and then diesel generating set is dashed forward
Load is so lost, and the diesel generating set worked normally at this time is often operated in high load capacity or even at full capacity operating mode section, dashes forward
Runaway of Diesel Engine can be caused moment by so losing load.This driving failure is also most serious in all kinds of driving failures, to diesel oil
The damage of machine is extremely serious.
In the prior art, a kind of method for tackling driving failure is the fuel supply terminated immediately to diesel engine, still
Diesel engine still can maintain the high speed of a period of time that can just be shut down after rotating due to inertia, and the inertia of this period revolves at a high speed
Turn still to be enough to damage diesel engine.
The method of another kind reply driving failure is the installation friction type brake piece near diesel engine rotating shaft, is fired in cut-out
While oil supply, diesel engine shaft is held tightly by brake(-holder) block.This scheme although shorten diesel engine height to a certain extent
The inertia high-speed rotating time, but friction plate also inevitably causes serious friction damage to diesel engine shaft.
The content of the invention
The purpose of the present invention is exactly to overcome the deficiency of the above-mentioned prior art, provides a kind of diesel generating set anti-joy ride device
And control method, it can prevent driving when major loop loses load suddenly.
The object of the present invention is achieved like this：A kind of diesel generating set anti-joy ride device, main generator pass through main disconnected
Road device powers to the load, it is characterised in that sets a bypass resistance cabinet and a failure monitoring system, the bypass resistance cabinet
By protecting contactor and load circuit main circuit breaker and being connected in diesel generating set output terminal, the status signal of main circuit breaker
And the working instruction signal of master control system is sent into the failure monitoring system, the output control protection of the failure monitoring system connects
The state of tentaculum.
A kind of control method of above-mentioned diesel generating set anti-joy ride device, it is characterised in that take the following steps：
A. the original state of main circuit breaker and protection contactor is separating brake；
B. detect whether to receive main circuit breaker combined floodgate work order：Otherwise original place is cycled；It is then to enter next step；
C. detect whether main circuit breaker is gate-dividing state：Otherwise original place is cycled；It is then to enter next step；
D. detect whether to receive separating brake work order：It is then return to step B；Otherwise next step is entered；
E. protection contactor is made to close a floodgate, and sends main disconnected device exception separating brake alarm, is requested stop.
The solution of the present invention, when main circuit breaker protectiveness or it is fault sudden shut off when, bypass resistance cabinet accesses electricity at once
Road can be effectively prevented from the generation of the high rotating speed runaway accident of diesel engine, more abundant to unit control system and operating personnel
Reaction time, reduce and operate the accident risk that brings in a hurry, enable unit according to normal procedure completion shutdown.

Part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
All other embodiments obtained without making creative work belong to the scope of protection of the invention.
Referring to diesel generating set anti-joy ride device circuit theory schematic diagram shown in FIG. 1.Main generator passes through main open circuit
Device powers to the load.Bypass resistance cabinet is by protecting contactor and load circuit main circuit breaker and to be connected in diesel generating set defeated
Outlet.Failure monitoring system receives the status signal of working instruction signal and main circuit breaker, the state of control protection contactor.
Referring to diesel generating set anti-joy ride device control method program flow diagram shown in Fig. 2.In frame 1, unit starts
The original state of work, main circuit breaker and protection contactor is separating brake.Into frame 2, detect whether to receive main circuit breaker conjunction
Lock work order：Otherwise original place is cycled；It is then into frame 3, whether detection main circuit breaker is gate-dividing state：Otherwise original place is cycled；
It is then to enter frame 4.In frame 4, detect whether to receive separating brake work order：It is to judge working properly, returns frame 2；Otherwise enter
Frame 5.In frame 5, protection contactor is made to close a floodgate, and send the alarm of main circuit breaker exception separating brake, and now requests are shut down.
Finally it should be noted that：The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although
The present invention is described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that：It still may be used
