Abstract
The invention relates to a device for separate delay starting of induced draft fans. The device comprises a plurality of induced draft fans and a induced draft fans control cabinet on a transmission side, and is characterized in that a master push-button is arranged inside the induced draft fans control cabinet on the transmission side, wherein the master push-button is connected with starting switches of the plurality of induced draft fans; and a time delay is arranged on the starting switch of each induced draft fans. The device for separate delay starting of induced draft fans is added with the time relays on the starting devices for the induced draft fans; the time delay is used to achieve the dela starting or shutdown in the whole starting process, so that the influences to power grid voltage when a plurality of devices are simultaneously started are reduced to protect the voltage of the power grid. The device for separate delay starting of induced draft fans is simple to install, and small in investment cost.
Description
Technical field
The invention belongs to the papermaking equipment technical field, particularly relate to many high-power electric appliance equipment and start simultaneously or close the protective device that causes the line voltage transient fluctuation---the machine of facining the wind divides platform delayed startup device.
Background technology
In paper industry, relate to many high-power electric appliance equipment, they start or stop all simultaneously can cause transient fluctuation to line voltage, causes appliance switch to damage; With the paper machine room Dryer Section of Paper Machine is row, and the blower fan control cubicle need operating personnel to go fore side to close down one by one during each starting (stopping), and can not unify blanking time at transmission side; When the paper machine ran well, one to six group of drying cylinder blower fan started work simultaneously, every with motor be level Four 15KW; Rated current 30A, when paper occurring breaking, 7 typhoon machines need decommission simultaneously; In the whole operation process, the startup of phase asynchronous uncle's cage or motor, electric current is 5-7 times; 7 15KW of separate unit paper machine machine that facings the wind will reach 1050A in moment by minimum 5 times starting current, will cause the line voltage transient fluctuation like this; Often cause main transmission frequency converter overvoltage tripping operation, fluctuation appears in the DCS system, and production is affected.
Summary of the invention
The objective of the invention is to overcome the defective of above-mentioned prior art, provide a kind of and realize that the time-delay distribution starts, the machine that facings the wind that line voltage is played a protective role divides platform delayed startup device.
The present invention realizes through following technical scheme:
A kind of machine that facings the wind divides platform delayed startup device; Comprise some facing the wind machine and the transmission sides machine control cubicle that facings the wind; It is characterized in that: total button is set in above-mentioned transmission side facings the wind the machine control cubicle; This total button links to each other with the starting switch of above-mentioned some the machines that facing the wind, and on the starting switch of each machine that facings the wind the set-up time relay.
The starting time of above-mentioned each time relay is set to 5-10S at interval.
Install the time relay additional on the starting switch that the machine that facings the wind of the present invention divides platform delayed startup device to be employed in the machine of facining the wind; Utilize this time relay to realize whole starting process delayed start-up or close; The influence that when thereby the reduction multiple devices start simultaneously line voltage is caused, the protection line voltage.It is simple that the machine that facings the wind of the present invention divides platform delayed startup device to install, and investment cost is little.
Description of drawings
Fig. 1 is the structure principle chart that one of them machine of facining the wind of the present invention divides platform delayed startup device, and KA is a relay among the figure, and KT is the time relay, and SB is a button, and KM is an A.C. contactor.
Embodiment
It is to be provided with to the facining the wind equipment of existing papermaking Dryer Section of Paper Machine system that the machine that facings the wind of the present invention divides platform delayed startup device; Improvements are on the starting switch of the machine that facings the wind 6 relay K A and time relay KT to be installed; Utilize the master control button to control 6 relays, concrete mechanism mode is: in transmission side facings the wind machine control cubicle master control cabinet, total button is set, operating position is at fore side; This total button is connected with the starting switch of all machines that facing the wind, and these several blower fans are parallel connection settings.Set-up time relay on the starting switch of each machine that facings the wind, employing delay effect are realized the different time startup of 7 blower fans or close that be 5-10S its blanking time; Specific operation process is: when the work of paper machine or when stopping, starting or when stopping total control switch (total button), first machine that facings the wind begins starting or stops; After 5 seconds, second machine that facings the wind will start or stop, during through 7 seconds; The 3rd machine that facings the wind will start or stop, and during through 10 seconds, such the 4th typhoon machine will start or stop; By that analogy, 7 typhoon machines of separate unit Dryer Section of Paper Machine start or stop and finish.
Claims (2)
1. the machine that facings the wind divides platform delayed startup device; Comprise some facing the wind machine and the transmission sides machine control cubicle that facings the wind; It is characterized in that: total button is set in above-mentioned transmission side facings the wind the machine control cubicle; This total button links to each other with the starting switch of above-mentioned some the machines that facing the wind, and on the starting switch of each machine that facings the wind the set-up time relay.
2. divide platform delayed startup device according to the described machine that facings the wind of claim 1, it is characterized in that: the starting time of above-mentioned each time relay is set to 5-10S at interval.
