Summary of the invention
Purpose of the present invention just is to overcome above defective, and provide a kind of and can set overload and short circuit current rated value, and the remote control of convenient operation and dual-use manual formula high-voltage safety switch.
The invention provides a kind of remote control and dual-use manual formula high-voltage safety switch, comprise insulated column, on reach lower conducting plate, switch alloy contact, magnetic conduction contact rod, piston bush, short circuit current coil, overload current coil, control box, it is characterized in that, do not comprise fuse, wherein: an end of described upper conductive plate connects the upper end wiring screw rod of described insulated column, and the other end is fixedly connected with described switch alloy contact; One end of described magnetic conduction contact rod contacts with described switch alloy contact, and the other end inserts described piston bush and is connected with the centre cap of described short circuit current coil by described piston bush; An exit of described short circuit current coil is connected on the copper sheet contact of lower end wiring screw rod of described insulated column; Insulation board one end of described insulated column lower end connects the lower end wiring screw rod of described insulated column, and the other end connects an end of described lower conducting plate, and the other end of described lower conducting plate is connected with described piston bush; One of them exit of described short circuit current coil and described overload current coil is connected to each other to centre cap to be connected with described piston bush or described lower conducting plate, and two control ends of described control box are connected with the exit of described short circuit current coil and described overload current coil respectively.
Further, described overload current coil is held a concurrent post switch with as electromagnet coil, utilizes infrared ray or the described electromagnet coil of other electronic telecontrol technology Remotes to come disconnection and the combined floodgate of the described switch alloy contact of remote control by described control box.
Further, the clamping ring that utilizes high-voltage insulating rod directly to catch on described magnetic conduction contact rod is manually controlled disconnection and the combined floodgate of described switch alloy contact.
Further, the load current value of described short circuit current coil and described overload current coil can be adjusted respectively.
Further, described short circuit current coil and described overload current coil are made by being wrapped in the outer field enamel covered wire of described piston bush insulating barrier.
Further, described piston bush is made by copper or stainless steel.
Further, described magnetic conduction contact rod is formed from steel.
Further, described upper lower conducting plate is made by copper or stainless steel.
Further, described control box is arranged on described insulation board.
than the existing high pressure drop switch that high-voltage fuse is housed, remote control of the present invention and dual-use manual formula high-voltage safety switch can accurately be set current value, and can distinguish setup control overload current and short circuit current rated value, when breaking down, high-tension line and equipment can in time disconnect high voltage source, again close a switch after discharging fault and just can work, can close a floodgate manually and disconnection and electronic telecontrol combined floodgate and disconnection, also can be used as the Automation of Electric Systems remote control switch, operation is very easy, can prolonged and repeatedly use, for future power equipment particularly rural power equipment realize that Automation of Electric Systems lays a solid foundation.
Because having overcome present high pressure drop switch, remote control of the present invention and dual-use manual formula high-voltage safety switch change that fuse is difficult, the problem such as difficult of closing a floodgate, therefore replaceable power high voltage drop switch in the market fully.
