17Ame+Fuse Combination

Drop out fuses and load-drop fuses are outdoor high voltage protection appliances. It is installed on the high voltage side of the distribution transformer or on the branch line of the distribution line. used as a short circuit of the transformer and the line, overload protection and split load current.
The drop fuse is composed of two parts:

An insulating bracket and a fuse tube. The static contact is installed at two ends of the insulating bracket, the movable contact is installed at both ends of the fuse tube, and the fuse tube is composed of an inner arc extinguishing tube and an outer layer.

It consists of a phenolic paper tube or an epoxy glass tube. The load drop fuse enhances the elastic auxiliary contact and the arc extinguishing cover to divide and combine the load current.

5,Easy to install

In electrical distribution, a fuse cutout or cut-out fuse is a combination of a fuse and a switch, used in primary overhead feeder lines and taps to protect distribution transformers from current surges and overloads. An overcurrent caused by a fault in the transformer or customer circuit will cause the fuse to melt, disconnecting the transformer from the line. It can also be opened manually by utility linemen standing on the ground and using a long insulating stick called a "hot stick".
Wholesale Fuse Cutout â??s Construction
The fuse elements used in most distribution cutouts are tin or silver alloy wires that melt when subjected to high enough current. Ampere ratings of fuse elements vary from 1 ampere to 200 amperes.
Standards
Up until the mid-1990s each manufacturer used their own dimensional standards for cutout design; by the late 1990s most cutouts were of an "interchangeable design". This design allows for the interchangeable use of cutout bodies and fuse holders manufactured by different vendors.

What Is A Fuse?
Fuses are also known as current fuses, and the IEC127 standard defines it as a "fuse body." It is primarily a function of current overload protection. When the circuit fails or abnormal, accompanied by rising current, and the rising current may damage some important devices in the circuit, it is possible to burn the circuit or even cause a fire.
If the circuit correctly install the fuse, then the fuse will rise in the current to a certain height and heat, when the fuse itself cut off the current, so as to protect the safe operation of the circuit.

Fuse Characteristics
Resistivity is large; low melting point.
Small size, easy to install
Disjunction capability precision, reliability
Different structural features, installation in various forms
Under normal conditions, the fuse has a long shelf life
Recoverable fuse, reset can be repeated use
Long life of the fuse, in case of fault-free circuit, synchronized with the life of the equipment

Structural Classification Of Thermal Fuse
organic type metal shell temperature fuse is a combination, the composition of the structure are:
1. Pin (A), 2. Sealed resin, 3. Insulating ceramic, 4. Fine spring, 5. Star reed, 6. Coarse spring, 7. wafer, 8. temperature sensing block, 9. The housing, 10 Pin (B).

When the temperature insurance is in normal operation, the current flows from the left lead to the sliding contact and flows through the metal housing to the right lead. When the external temperature reaches the predetermined temperature, organic matter can melt melt, the compression spring will become loose. That is, spring expansion, sliding contact (slidingcontact) and the left side of the separation. The circuit will cut off, the current between the sliding contact and the left lead is cut off. the temperature fuse will fail and can not be used again.

2, easy to melt alloy wire thermal fuse has ceramic shell and square shell, its temperature sensing element is a fusible gold.
Product structure: is the axis of the symmetrical lead, fusible alloy wire, and resin mixture and insulated porcelain tube, plastic shell.

When the temperature rise of the heating element is set to a temperature, the resin mixture begins to liquefy, when the melting point is reached, with the help of the resin mixture (increasing the surface tension of the melted alloy), has been molten alloy wire in the resin mixture under the action of tension, quickly to both ends of the wire as the center shrink into a spherical, and thus permanently cut off the circuit.

Technical Parameters And terminology Of Thermal Fuses
(1) Rated operating temperature (Tf):
The temperature fuse is tested according to the standard method to change the temperature of its conductive state. According to IEC6091 standards-based security provisions, the temperature fuse must be operated within the rated operating temperature + 0 / -10 C (the Japan Electrical Supplies Act provides a tolerance range of ± 7 C).
(2) Operating temperature Found:
The temperature fuse is heated in the silicone oil tank at a rate of 0.5-1 C per minute, detection current is less than the fusing temperature measured at 10mA condition. It is the actual operating temperature of the temperature fuse.
(3) Holding temperature (Th):
When the temperature fuse passes the rated current, can hold for 168 hours without changing the maximum temperature of its conductive state.
(4) limit temperature (Tm):
Temperature fuse can withstand the maximum temperature for 10 minutes reconnection phenomenon never occurs.
(5) Rated current (Ir):
The maximum current that the temperature fuse can carry.
(6) Rated voltage (Ur):
Temperature fuse maximum operating voltage.
