The frequency of electric fish machine is the most appropriate

Electric fish machine don't have large voltage in water. With voltage from 600 V to 600 V, it can go through the mixing water, and can have very good fishing effect, if use high voltage in mixing water, fish will swim underwater. Because water is muddy, we cannot see fish clearly under the water.

Rich fishing apparatus for your answer

Using CLP fish machine friends all know that the same type of electric fish machine in very clear water and a little water when using the effect is not the same, why this would happen, because the water and mix water conductivity is different, the conductivity of the water is relatively low, the electrical conductivity of the mixed water, so when the two kinds of fish in the water electricity effect certainly is not the same, want to change the working voltage of electric fish machine can change the fishing effect.

Mixing the water electric fish machine don't have too high voltage, voltage from 600 v to 600 v is ok, in this voltage range, can very good through the mix water, can have very good fishing effect, if mix water using high voltage, fish is easy to electricity underwater, original water is muddy, cannot see fish electric sank under the water.

Water fishing machine to high working voltage, the voltage of rectifier to be the best can reach more than 850 v to 1100 v, if it is including peak voltage, that is in 1200 v to 1500 v can achieve good effect

Fruit, the high voltage in the low conductivity water can have good penetration, in order to increase the depth of the electric fish, it is also is to increase the area of waterline dew copper, dip net and line.

Fish and mix water and water activity is not the same, the water in the fish is very active, run fast, mix the fish in the water activity is low, fishing, electricity in the water to avoid the whole ", otherwise the fish will run far away, you won't think electric power.

Summer fish is relatively active, need to adjust machine power to capture. Power relatively mild winter fish, don't too.

(if the machine with gear, the output frequency can adjust frequency size, reference this article with a voltage regulation effect)

High frequency machine: fish circuit attached to the front, please, to discuss how to speed up the frequency.

The principle of electric fish machine

Electric fish machine is low voltage, high current power transformation into high voltage and instantaneous large current pulse dc converter.

Its components have two: one is the inverter part (before); Second, the rectifier part pulse discharge (after class).

Part one, the inverter (before) :

Must have enough output power and output voltage. If the output power is not big, it's no use even in high voltage, it is because the water resistance. The voltage is too low, too small current through the water ;Voltage is too high, will increase the output resistance and load capacity and poor, and components of high voltage, high standard of transformer insulation and so on, this also reduces the reliability. General output voltage (light) in 400-1000 - v, output power according to use the occasion to decide, at least 150 w (with more than 220 v150w send white light bulbs).Because single bearing power should not be more than 800 w, 800 w with input current will reach 70 a, and the biggest back 40 ah battery is in less than a few hours, if used in the ship power can reach 1 to 2 kw.

In existing application of switch power device, a platinum contacts the transistor, SCR, MOS tubes, etc., of the transformer is silicon steel, ferrite core, etc.

Making electric fish machine circuit has a lot of kinds most USES push-pull. In the switch power device midfielder tube has the highest efficiency, and platinum mechanical switch of the lowest efficiency.

In production, the winding of the transformer is critical. In the application of the transformer, silicon steel sheet core material of the work frequency is low, generally no more than 10 KHZ, so the transformer coil is more, with a large amount of copper; With ferrite core working frequency is high, generally 20 KHZ to 300 KHZ, transformer, wire loops, less so with the less amount of copper; For silicon steel core material, generally speaking, there are E shape, C shape, and the appearance of the ring. E in the selection of core making simple, the leakage inductance of the larger; Generally choose C shape, as a control fishing machine transformer; Ring of switch power is higher, annular transformer iron core can be used to power distribution equipment, the effect is very good, but the wound is trouble. Insulation is more difficult, ferrite high working frequency, small volume, less number of turns, so it's best to winding. In order to overcome the high frequency skin effect, generally use more shares and round. Low-frequency core of low working frequency, single strands of wire winding, winding can be more convenient for stocks and round.

Second, the rectifier part pulse discharge (after class).

Pulse discharge part of the essence of which is to rectifying the high voltage direct current (dc) after storage, water discharge via the capacitance in an instant, the process of capacitor energy storage instantaneous discharge can improve the instantaneous power, achieve instantaneous maximum pulse power, in order to achieve the best effect of electric fish. But the total power will not change, it will remain to transformation and conservation, namely the total input power is greater than output power.

Rectifier can be used double rectifier, bridge rectifier is also available. If the transformer output voltage is low, it can increase the voltage with double pressure. If the transformer output voltage is higher, you need to use the bridge rectifier. Low frequency machine common diode rectifier can be used, the high frequency machine with schottky diode. Can choose non-polar capacitor energy storage capacity, also can choose electrolytic capacitor. Large capacity of electrolytic capacitor is small in size, but the performance is inferior to non-polar capacitors.

Pulse discharge part, average discharge device with relay, triode or output field effect tube, silicon controlled rectifier, etc. Relay is the most simple, but there is noise, and very easy to burn out contact; Worst triode or the reliability of the field effect tube output, be especially careful when using, avoid touch in water (that is, output short circuit);Silicon controlled one of the best, but the turn-off thyristor is difficult, because after the rectification is direct current, once triggered thyristor that is out of control in dc. The solution is to use an inductance capacitance oscillation of the pulse force thyristor turn-off. Discharge frequency, it is a critical index of the floating fish, average discharge frequency should be adjustable between 5-80 hz. with more than 555 good harmonic oscillation frequency, simple control.

Main oil transformer size work parameter field effect tube decided how much if I need to change a small power machine big need to increase in large transformer winding again power tube of the original machine over-current protection accordingly

There is a high frequency machine for power don't quite understand, I ask you:

A nominal 500 w high frequency machine, load (water) 8 ~ 9 a battery output current, battery voltage 12 v.

High voltage output load (water), 560 v, current 0.8 A (digital display table test)

A nominal 500 w high-frequency machine: load (water) 8 ~ 9 a battery output current, battery voltage 12 v.

High voltage output no-load 230 V, load (water) 260 V, current 0.45 A (digital display table test)

Note: the digital display table not bad
