Description
Technical Field
The invention relates to the field of monitoring devices, in particular to a residual electricity discharging device of a high-voltage isolating switch.
Background
The high-voltage isolating switch is an important switching device in an electric system of a power plant and a transformer substation and needs to be matched with a high-voltage circuit breaker for use. The isolating switch is suitable for indoor devices with three-phase alternating current of 50Hz and rated voltage of 12 KV. The device is used for switching on, switching off or switching over the line under the condition of no load and voltage of the high-voltage equipment. The main functions are as follows: the safety of the high-voltage electrical appliance and the device during maintenance work is ensured, the voltage isolation function is realized, the high-voltage electrical appliance and the device cannot be used for cutting off, inputting load current and cutting off short-circuit current, and only can be used for certain switching operation without generating strong electric arcs, namely the high-voltage electrical appliance and the device do not have the arc extinguishing function; the voltage class is divided into single-column type, double-column type and three-column type according to the number of the insulating support columns, and each voltage class has optional equipment.
The high-voltage isolating switch ensures the safety of high-voltage electrical appliances and devices during maintenance work and plays a role of isolating voltage, contacts of the high-voltage isolating switch are completely exposed in the air and have obvious disconnection points, the isolating switch is not provided with an arc extinguishing device, so that the isolating switch cannot be used for cutting off load current or short-circuit current, otherwise, under the action of high voltage, the disconnection points generate strong electric arcs and are difficult to extinguish by themselves, and even flashover (relative ground or interphase short circuit) can be caused, equipment is burnt, the personal safety is threatened, and the serious accident of pulling the isolating switch with load is the so-called 'serious accident'.
The high-voltage isolating switch can also be used for carrying out switching operation of certain circuits so as to change the operation mode of the system. For example: in a dual bus circuit, a high voltage isolation switch may be used to switch the circuit in operation from one bus to another
The high-voltage isolating switch is the high-voltage electrical equipment with the largest use amount and the widest application range in the power system. However, since the main function of the high-voltage isolating switch is to perform an isolating function, load current and fault current are not switched on and off, the high-voltage isolating switch is in a closed state for a long time and is operated less frequently, and the high-voltage isolating switch has a relatively simple structure and is easy to manufacture, the high-voltage isolating switch is electrical equipment which is most seriously attached by manufacturing and using departments. Manufacturers often produce the high-voltage isolating switch as an additional product matched with the circuit breaker, and the design, material selection, processing technology, assembly debugging, quality control and the like of the product are all placed at secondary positions, so that the performance and the quality of the high-voltage isolating switch are difficult to ensure compared with the circuit breaker; the operation department ignores the management, especially the maintenance management, of the high-voltage isolating switch in the professional management work of the high-voltage switch, the maintenance is in a free state, no uniform and legal maintenance rules exist, the phenomenon of long-term overhaul generally exists, and especially the bus isolating switch is basically not overhauled. The high-voltage isolating switch is actually in a state of 'repair is not damaged, repair is carried out only when the high-voltage isolating switch is damaged' and repair is carried out when the high-voltage isolating switch is damaged in operation.
When the high voltage isolation switch opens the circuit, still can have remaining electric current in the general circuit, if not put the remaining electricity in the circuit totally, will take place to hinder the people accident, generally put remaining electric current, all through stewing for a long time, perhaps discharge by the artifical handheld earthing rod, unusual inconvenient, also unsafe. It is highly desirable to design a tool that can dissipate the residual current in the circuit.
