Abstract
The utility model discloses a wind power and gas power lock protection device, wherein a blower fan normally open contact K1 and a gas circuit breaker normally open contact K2 are in series connection and then connected to a protection device (2) through the load side chamber binding posts (1) of a high-voltage explosion-proof switch. According to the wind power and gas power lock protection device, after the prior protection is replaced by the protection device (2), the disadvantage of the prior protection device is overcome, and the characteristics are provided as following: 1, a lock action value and the action time can be accurately searched; 2, the action is sensitive and reliable, and mis-operation or resist-operation is prevented; and 3, whether the high-voltage explosion-proof switch trips for wind power or gas power lock protection is observed clearly through an observation window, which is convenient for fault determination and elimination.
Description
Technical field
The utility model relates to the protective device that a kind of the utility model relates to a kind of colliery high-explosive switch, particularly high-explosive switch.
Background technology
The protective device that uses due to the colliery high-explosive switch does not possess wind-powered electricity generation and gas electric shutting function, can only utilize the decompression coil of high-explosive switch to realize the locking trip protection.Principle with the lock between air and electricity protection describes: the power supply that utilizes a pair of normally opened contact control high quick-fried latch switch (hereinafter to be referred as high-explosive switch) the decompression coil on the fan switch control loop, when the fan switch adhesive, its normally opened contact is closed, connect high-explosive switch decompression coil power, can close a floodgate; After fan switch tripping operation, disconnections that reset of its normally opened contact, high-explosive switch decompression coil losing electricity, the high-explosive switch tripping operation realizes lock between air and electricity protection.Gas electric shutting is similar to the lock between air and electricity protection philosophy, and difference is that it utilizes a pair of normally opened contact on gas breaker.
Due to the limitation of protected device, there is following problem in this latch-up protection: 1, all can not inquire about block action value and operate time; 2, high-explosive switch tripping work or misoperation appear in occasional; 3, whether the electrical source of power switch trip causes because of wind-powered electricity generation or gas electric shutting action, is difficult to judgement, is not easy to inquiry, analysis and the eliminating of fault.
Summary of the invention
The technical problems to be solved in the utility model: a kind of wind-powered electricity generation and gas electric shutting protective device are provided, with solve the block action value and can not inquire about operate time, high-explosive switch tripping work or the misoperation occasional occurs and whether the electrical source of power switch trip causes this three problems because of wind-powered electricity generation or gas electric shutting action.
The technical solution of the utility model is: add new protective device to replace the existing protected mode of high-explosive switch; namely respectively to get a pair of normally opened contact from fan switch and gas breaker respectively; be connected with the high-explosive switch terminal after connecting through the locking line, then be connected in protective device.When fan switch tripping operation or gas exceeding limit cause disconnecting the instrument action, send signal by protective device, make the shunt opening coil motion, realize the latch-up protection action.
The utility model utilizes protective device to carry out track remodelling, wind-powered electricity generation and gas electric shutting defencive function is improved more reliable.
Description of drawings
Fig. 1 is the front protection philosophy figure of transformation;
Fig. 2 is the rear protection philosophy figure of transformation.
Embodiment
As Fig. 2, be respectively to get a pair of normally opened contact K1 and K2 from fan switch and gas breaker respectively, through being connected with high-explosive switch load side chamber binding post 1 after the series connection of locking line, then be connected in protective device 2.The protective device 2 here uses the GCS2321 type high-voltage complex protection device (design parameter is as follows) of Nanjing state occasion; when fan switch tripping operation or gas exceeding limit cause the cutoff instrument action; send signal by protective device 2, make the shunt opening coil motion, realize the latch-up protection action.Device after improvement can select whether to continue to use the decompression coil, must guarantee that the decompression coil is in closure state if use; If do not use, can dismantle.4# in Fig. 2 and 6# terminal are the 100V power supply.
State's occasion comprehensive protector main specifications, model and Specifeca tion speeification:
Claims (1)
1. wind power gas electric shutting protective device; comprise high-explosive switch load side chamber binding post (1), blower fan normally opened contact K1 and gas breaker normally opened contact K2, it is characterized in that: blower fan normally opened contact K1 and gas breaker normally opened contact K2 series connection are connected in protective device (2) by high-explosive switch load side chamber binding post (1).
