摘要： One embodiment of a disclosed cable protection device connected between the positive and negative wires of the cable that provides an efficient method of protection from overheating of the device due to changes in temperatures with minimal power dissipation. The cable protection device includes a temperature monitoring device that continuously senses the temperature of the cable and device to check for overheating. A controller connected to the temperature monitor sends out an alarm message and a control signal to either an actuator circuit or a crowbar function circuit. The actuator circuit can send out current pulses to the adapter indicating the adapter to lower its current limit, so that the device can still keep charging and is not over heated. The crowbar function circuit causes the adapter to turn off power to the cable in order to provide burning of the device or connector due to overheating.

摘要： The invention relates to fluid drive systems used in fluid wells and brake systems for permanent magnet wellhead direct drives. The braking controller connects or disconnects a brake resistor from a back EMF. A variable frequency drive (VFD) drives the motor and communicates with the control circuitry of the brake controller. The control circuitry monitors the brake resistor and depending on the rotational speed and direction of the motor and operating state of the VFD, disconnects or connects the brake resistor. If the direction of the motor is in reverse and above a threshold speed, it connects the brake resistor. If the direction of the motor is in reverse and below the threshold speed, the control circuitry dissipates stored back EMF through the brake controller. The amount of stored back EMF corresponds to the time to empty a pump.

摘要： An electrical power supply includes a power input interconnected with a power source that supplies input power having a voltage exceeding a predetermined voltage threshold, e.g. a low voltage threshold. A power conversion arrangement converts the input power to output power having a voltage at or below the voltage threshold, and the low voltage power is supplied to a power outlet. An over-voltage protection arrangement, in the form of a voltage sensing circuit, is operable to detect the voltage of output power from the power supply and to discontinue the supply of power to the power outlet in the event power supplied to the power outlet has a voltage that exceeds the low voltage threshold. The over-voltage protection circuit is incorporated in a circuit board adapted to be plugged into a primary circuit board of the power supply. The over-voltage protection circuit establishes a path through which power is communicated from the power conversion arrangement to the power outlet, and creates a short circuit condition when power supplied to the power outlet exceeds the low voltage threshold.

摘要： A soft heating element, utilizing electro conductive textile threads as a heating means having additional safety functions as TCO (thermal cut-off) and TSL (temperature self-limiting) devices. The thermal cut-off function is achieved through melting of the electro conductive threads at the temperatures above 120° C. and below 350° C., which results in termination of electrical continuity in the heating element. The temperature self-limiting capability is achieved through a heating thread electrical resistance increase during slow elevation in its temperature, which is below its melting point. Methods of electrical and mechanical connection between heating threads and metal conductors, utilizing winding of connections with flexible strands of fibers or wires, with optional subsequent placement of a rigid mechanical fastener over the winding. Method of providing electrical redundancy of heating circuits by stitching, laminating, weaving or knitting an electrically conductive thread across the multiple runs of the heating thread.

摘要： A household electrical service (10) is protected against overheating by running a sensor line or wire (36 or 38), coextensively together with hot, neutral and ground lines or wires (12, 13, 14 or 31, 32, 33), from a power company hookup (50) to a main breaker switch (18), and from respective branch circuit breakers (19) throughout the branch circuits (21, 22). The sensor line or wire (36 or 38) may be a length of heat fusible or otherwise temperature variant material which has a load end connected to ground and a source end connected to a control circuit (51) which trips the breaker (18 or 19) when an overtemperature condition melts the wire. Protection is extended through to individual devices (43) by continuing the sensor wire through the device cord (42). For this purpose, a plug ground prong (46) and receptacle ground prong connection (45) provide isolated ground and sensor wire connections. In a modified installation, fiber optic paths (38') are used in place of conductive wires and LED circuits replace load end ground connection.
