Abstract
The utility model relates to a pulse generator for electric pulse prawn trapping device, solving the problem that the pulse transformer is easy to burn. The utility model comprises a pulse generator circuit and a sealed barrel as the shell, wherein, the pulse generator circuit comprises an energy storage capacitance, a trigger, controllable silicon, a forced turning off circuit by the controllable silicon and a pulse transformer; the sealed barrel is provided with a cable pipe joint. The utility model is characterized in that the trigger is communicated with the power supply positive pole through the relay contact of a delay circuit, being used for an electric pulse prawn trapping device in fishery prawn trapping.
Description
The utility model relates to the auxiliary electronic equipment of fishery shrimping, especially the impulse generator of electric pulse prawn trapping device.
The impulse generator of electric pulse prawn trapping device can be transformed into the 400V direct current 0-60Vop, frequency is that 5Hz, pulsewidth are the low voltage electric impulse of 0.3ms; and offer the pulse current that the network interface electrode is emitted certain intensity and can not be endangered shrimps life by pulse transformer; to stimulate shrimp from the seabed take-off; in the shrimping operation, can receive and improve output and catch the effect of staying little protection aquatic resources greatly, therefore welcome by the fisherman.But the impulse generator of electric pulse prawn trapping device burns out the equipment fault of pulse transformer to happen occasionally, trace it to its cause is to add in the galvanic original state of 400V at impulse generator, because controllable silicon forces the voltage that the electric capacity in the breaking circuit also is not charged to is enough to make the controllable silicon shutoff, and the trigger impulse of trigger has been opened controllable silicon, form the controllable silicon normal open and the no pulse generation, pulse transformer is burnt out.Force breaking circuit, pulse transformer to be sealed among the cylindrical shell owing to form energy storage capacitor, trigger, controllable silicon, the controllable silicon of impulse generator, and in cylindrical shell, fill paraffin, therefore return in time to overhaul and cause difficulty.
The purpose of this utility model provides a kind of impulse generator of electric pulse prawn trapping device of dependable performance.
The utility model comprises that pulse-generator circuit and the sealed cylinder as shell that energy storage capacitor, trigger, controllable silicon, controllable silicon force breaking circuit, pulse transformer to constitute form, and the electrode input end that it is characterized in that trigger connects positive source by the relay contact of the delayer that a delay circuit constitutes.
Because the utility model is provided with delay circuit before trigger, when input 400V DC voltage, it is 0.1 second that controllable silicon forces the electric capacity initial charge of breaking circuit to need the time, and delayer time-delay 2-3 just connects flip-flop operation voltage after second, guaranteed to force the charging interval of breaking circuit electric capacity, trigger sends pulse and removes the conducting controllable silicon then, avoids the controllable silicon original state to close and constantly burns out the defective that pulse becomes device.
Accompanying drawing 1 expression circuit diagram of the present utility model, C represents energy storage capacitor among the figure, R2 represents resistance, Q1 represents controllable silicon, Q2 represents the reverse protection diode, and L1 represents the thyristor commutation inductor, and C2 represents the thyristor commutation capacitor, B1 indicating impulse transformer, above element and trigger are formed the prior art pulse-generator circuit; The time delayer circuit that expression resistance R 1, capacitor C 1, relay J 1 constitute in the frame of broken lines among the figure, J1-1 is a relay contact, trigger is connected power supply during this closing of contact.
Accompanying drawing 2 is sealed cylinders of the present utility model, its two ends adopt the flange seal structure of band watertight cable pipe joint to irritate the sealing means of wax to replace cylindrical shell, 1 expression cylindrical shell among the figure, blue circle 2 is managed in the end of cylindrical shell, o shape sealing ring is arranged between flange end cap 3 and the shell flange circle, and 4 is the watertight cable pipe joints that are connected in the flange end cap outside among the figure.
Realize that best way of the present utility model is resistance R 1 employing 20K Ω/25W resistance of delay circuit, capacitor C 1 adopts 2200uf/50V electric capacity, and relay J 1 adopts the JR-5M relay.
