Technical Field
The invention relates to the technical field of pulse power, in particular to a technology for connecting a pulse heavy-current device and a load.
Background
The pulse high-current device has very important position in the technical field of pulse power, and has important function in a plurality of application fields, such as plasma pinch, plasma focus and strong pulse magnetic field which are widely applied in controlled nuclear fusion research, electromagnetic emission, electric explosion conductor, electromagnetic forming, electric armor, electromagnetic pulse simulation and liquid electric explosion, even aircraft deicing, metal nano material preparation and the like. In order to obtain pulse current with amplitude and gradient as large as possible under certain voltage and capacitance, pulse capacitors with small inductance should be used to discharge to load in parallel, and coaxial cables are used as connecting wires, and the current of the pulse capacitors flows out from the inner core of the cable and flows back from the outer core of the cable. In order to enable the currents output by all the capacitors to reach the load at the same time when the pulse capacitors included in the pulse are arranged, namely, the currents output by all the pulse capacitors connected in parallel can be superposed at the load to generate the pulse current with the maximum amplitude, the connection length of coaxial cables between all the capacitors and the load in the pulse high-current device should be as same as possible. Generally, a capacitor included in a pulse high-current device does not exist independently, and the capacitor needs to form a module with complete functions with a discharge switch, a protection circuit, a control circuit and the like to complete a discharge process, and at the moment, connection lines between all capacitors and a load are connection lines between all modules and load time. In addition, when the pulse high-current device comprises a plurality of modules with complete functions, the discharge time sequence of the modules can be controlled to complete the continuous discharge of the load so as to complete specific requirements.
Due to the wide application of the pulse high-current device, different electro-physical effects can be generated when the structure and the characteristics of the load are different. When one pulsed high-current device supplies excitation current to a plurality of loads, sometimes the connection mode of the plurality of loads needs to be changed according to the application requirements so as to achieve a plurality of application conditions. How to stably and efficiently transmit the pulse current generated by the pulse large-current device to the load, and to change the combined connection mode of all the loads under the condition of a plurality of loads, and to expand the connection method according to the number of modules with complete independent discharge functions and the number of the loads included in the pulse large-current device is a problem which needs to be mainly solved at present.
Disclosure of Invention
The invention aims to solve the problems that when a pulse high-current device comprising a plurality of complete independent discharge functional modules is connected with a plurality of loads, pulse current generated by the pulse high-current device needs to be stably and efficiently transmitted to the loads, the connection mode of the plurality of loads can be changed, and the requirement of expanding according to the number of the complete independent discharge functional modules and the number of the loads can be met, and provides an expandable and variable combined load connection method of the pulse high-current device.
The technical scheme adopted by the invention is as follows:
an expandable and load-variable combined connection method for a pulse high-current device comprises a connection structure, a multi-load variable combined connection mode and an expanded connection mode.
The connecting structure comprises a load, a load input/output end, a load input/output connecting structure, a confluence structure, an output coaxial cable and a pulse capacitor of the module.
The load is used for receiving the excitation pulse current provided by the pulse high-current device to generate an electro-physical effect.
The load input and output ends are nodes between the loads and the confluence structure, and the connection between the loads and the confluence structure and the series-parallel combination connection mode between different loads are realized by using the input and output connection structure on the load input and output ends.
The load input and output connection structure is used for connecting the load input and output ends of the loads with the confluence structure or connecting the input and output ends of different loads, so that different series-parallel combination modes among the loads are realized.
The convergence structure is used for converging the output pulse current of the modules and distributing the converged total current to each load, the convergence structure is a junction between the pulse heavy current device and the load, and comprises an input convergence first plate, an input convergence second plate, a measuring structure and an output convergence plate, and the measuring structure is positioned between the input convergence first plate and the input convergence second plate and used for placing equipment for measuring the total current.
The output coaxial cables are consistent with the pulse capacitors of the modules in number and used for outputting pulse currents after the pulse capacitors are discharged, in order to ensure that currents output by all the pulse capacitors connected in parallel can be superposed at a load to generate pulse currents with the maximum amplitude, the lengths of the output coaxial cables of all the pulse capacitors should have the same length, the inner cores of the output coaxial cables are connected with the positive electrodes of the pulse capacitors and the input confluence plate of the confluence structure, and the outer cores of the output coaxial cables are connected with the negative electrodes of the pulse capacitors and the output confluence plate of the confluence structure.
The pulse capacitor of the module is an energy storage element of a pulse high-current device, when the discharge switch is in short circuit, excitation pulse current is provided for a load, the positive pole of the pulse capacitor is connected with the inner core of the output coaxial cable to serve as a current outflow end, and the negative pole of the pulse capacitor is connected with the outer core of the output coaxial cable to serve as a current return end.
The multi-load variable combination connection mode mainly means that when the pulse high-current device provides excitation pulse current for a plurality of loads, the series-parallel connection structure of the plurality of loads is changed according to application requirements, for example, under the condition of two loads, the two loads have two combination modes of parallel connection and series connection; under the condition of three loads, the three loads have four combination modes of all parallel connection, all serial connection, 2 serial connection and 1 parallel connection, 2 parallel connection and 1 serial connection, and the like. When the connection modes of a plurality of loads need to be changed, the series-parallel connection combination mode of the plurality of loads can be realized by changing the connection positions of the input and output ends of each load and the bus structure. For example, under the condition of two loads, a load 1 and a load 2 are respectively marked, the input and output ends of the two loads are respectively connected with an input bus bar two plate and an output bus bar plate of a bus structure to realize a full parallel connection mode of the two loads, when the input end of the load 1 and the output end of the load 2 are kept unchanged, the connection between the output end of the load 1 and the input end of the load 2 and the bus structure is cancelled, and then the output end of the load 1 and the input end of the load 2 are connected to realize a full series connection mode of the two loads. Under the condition of three loads, respectively marking a load 1, a load 2 and a load 3, and respectively connecting the input and output ends of the three loads with an input bus bar two plate and an output bus bar plate of a bus structure to realize a full parallel connection mode of the three loads; on the premise of full parallel connection, when the input end of the load 1 and the output end of the load 3 are kept connected unchanged, the connection of the output end of the load 1, the input end of the load 3 and the input and output ends of the load 2 with a confluence structure is cancelled, so that the output end of the load 1 is connected with the load 2 and the input end, and then the output end of the load 2 is connected with the input end of the load 3, so that the full series connection mode of the three loads is realized; on the premise of full parallel connection, the connection of the load 3 is kept unchanged, the connection of the output end of the load 1, the input end of the load 2 and the confluence structure is cancelled, and then the output end of the load 1 is connected with the load 2 and the input end, so that the connection mode that 2 loads are connected in series and then connected with another load in parallel is realized; on the premise of full parallel connection, when the input end of the load 1 and the output end of the load 3 are kept connected unchanged, the connection between the input end and the output end of the load 2 and the confluence structure is cancelled, the input end of the load 1 and the input end of the load 2 are further connected, the output end of the load 1, the output end of the load 2 and the input end of the load 3 are connected, so that the connection mode that 2 loads are connected in parallel and then connected in series with one another is realized, the connection mode is suitable for the serial number of any three loads, and the representation with the load label is only clear and convenient; by analogy, under the condition that a plurality of loads exist, the series-parallel combined connection mode is still expanded according to the connection mode and the idea.
The expanded connection mode mainly means that when the number of modules with independent and complete functions contained in the pulse high-current device is increased, namely pulse capacitors of the modules are increased, the bus structure can increase and output coaxial cable interfaces according to the number of actual output coaxial cables, and when loads are increased, the bus structure can also increase and load interfaces according to the number of actual loads. The input confluence plate and the output confluence plate of the confluence structure are respectively used for connecting an inner core and an outer core of an output coaxial cable of the pulse capacitor, so that the purpose of converging pulse current output by the pulse high-current device is achieved, and the converged current is transmitted to the input confluence plate through the current measuring point and then distributed to each load. In the practical application process, when the pulse capacitor of the module is increased, the input collecting plate and the output collecting plate need to be increased according to the number of the output coaxial cables, and the connecting structure of the output coaxial cables is increased, so that different shapes can be changed according to the practical situation; similarly, when the load is increased, the input and output bus plates also need to be connected with the load input and output ends according to the number of the increased loads, and different shapes can be changed according to actual conditions.
Has the advantages that: the method can stably and efficiently transmit the pulse current generated by the pulse high-current device to the load when the pulse high-current device comprising the plurality of complete independent discharging functional modules is connected with the plurality of loads, can change the connection mode of the plurality of loads according to application requirements when the plurality of loads exist, and can expand the connection according to the number of the complete independent discharging functional modules and the number of the loads.

the multi-load variable combination connection mode is that when the pulse high-current device provides excitation pulse current for n loads, the series-parallel connection structure of the n loads is changed according to application requirements, for example, in the case of two loads, the two loads have two combination modes of parallel connection and series connection; under the condition of three loads, the three loads have four combination modes of all parallel connection, all serial connection, 2 serial connection and 1 parallel connection, and 2 parallel connection and 1 serial connection, and by analogy, when the connection mode of n loads needs to be changed, the series-parallel connection combination mode of a plurality of loads can be realized by changing the connection position of each load input/output end and the confluence structure; for example, in the case of two loads, they are respectively named: the input and output ends of the two loads are respectively connected with the input confluence two plates and the output confluence plates of the confluence structure to realize a full parallel connection mode of the two loads, and when the input end of the load 1 and the output end of the load 2 are kept unchanged, the connection between the output end of the load 1 and the input end of the load 2 and the confluence structure is cancelled, so that the full series connection mode of the two loads is realized after the output end of the load 1 and the input end of the load 2 are connected; under the condition of three loads, the three loads are named as a load 1, a load 2 and a load 3 respectively, and the input and output ends of the three loads are connected with an input bus bar two plate and an output bus bar plate of a bus structure respectively to realize a full parallel connection mode of the three loads; on the premise of full parallel connection, when the input end of the load 1 and the output end of the load 3 are kept connected unchanged, the connection of the output end of the load 1, the input end of the load 3 and the input and output ends of the load 2 with a confluence structure is cancelled, so that the output end of the load 1 is connected with the load 2 and the input end, and then the output end of the load 2 is connected with the input end of the load 3, so that the full series connection mode of the three loads is realized; on the premise of full parallel connection, the connection of the load 3 is kept unchanged, the connection of the output end of the load 1, the input end of the load 2 and the confluence structure is cancelled, and then the output end of the load 1 is connected with the load 2 and the input end, so that the connection mode that 2 loads are connected in series and then connected with another load in parallel is realized; on the premise of full parallel connection, when the input end of the load 1 and the output end of the load 3 are kept connected unchanged, the connection between the input end and the output end of the load 2 and the confluence structure is cancelled, the input end of the load 1 and the input end of the load 2 are further connected, the output end of the load 1, the output end of the load 2 and the input end of the load 3 are connected, so that the connection mode that 2 loads are connected in parallel and then connected in series with another load is realized, and the like; when m loads exist, the series-parallel combination connection mode is still carried out according to the connection mode, and m is smaller than n.
3. The expandable and load-variable combination connection method of a pulsed high-current device according to claim 1, characterized in that the expandable connection method specifically comprises:
the expanded connection method is that when the number of modules with independent complete functions contained in the pulse high-current device is increased, namely: when the pulse capacitors of the modules are increased, the confluence structure can increase and output coaxial cable interfaces according to the number of the actual output coaxial cables, and when the load is increased, the confluence structure can also increase and load interfaces according to the number of the actual load; in the practical application process, when the pulse capacitor of the module is increased, the input confluence first plate and the output confluence plate need to increase the number of the output coaxial cables according to the increase of the number of the output coaxial cables, and at the moment, different shapes can be changed according to the practical situation; similarly, when the load is increased, the input and output end connection structures of the input and output bus plates also need to be increased according to the number of the increased loads, and different connection structures can be changed according to actual conditions.
