Abstract
The present invention relates to a high-voltage fast power supply device crossing substations, which is suitable for high-voltage power supply systems, especially power supply networks of railway automatic blocking signal devices, and belongs to power supply circuit devices. The present invention is mainly characterized in that a substation crossing switch cabinet is connected between a first feedback cabinet and a second feedback cabinet of each middle distributing substation, and a substation crossing switch primary circuit and a substation crossing action secondary circuit are arranged. When the power cut voltage loss of the substation meets certain conditions, an associated relay in the secondary circuit is switched on. A substation crossing switch in the primary circuit is switched on so that a power supply of an adjacent substation at a side with power is transmitted to an adjacent substation at a side without power through the substation crossing switch, and substation crossing power supply is realized. The problem that the normal use of the automatic blocking devices is influenced by the power cut of the distributing substations is solved.
Description
The present invention relates to circuit arrangement for powering, be applicable to that high voltage supply system is particularly suited for the supply network of railway automatic anodizing equipment.
In the patent No. is 4354215 United States Patent (USP), disclose a kind ofly, can protect native system to power continuously by the high-speed switch contactor of rationing the power supply, resistor, the power distribution system secure protective device that constitutes such as switch contact at a slow speed.
The supply power mode of China railways signal automatic blocking is at present, the two independent power source special is exported by distribution substation, each loop powers to signal box as active and standby power supply respectively behind voltage regulator simultaneously, when a certain loop has a power failure for some reason, another ring current drops into automatically, to guarantee uninterrupted power supply.But in view of various places condition difference, some high voltage power distribution is a single power supply, also has the power supply of some unreliable, and therefore normal the generation influences automatic anodizing equipment and normally use because supply arm has a power failure, and upset transport order.
Purpose of the present invention is exactly to solve the above-mentioned problem that influences the normal use of equipment because of the supply arm power failure, design a kind of electric power supplying apparatus cross substations, when this distribution substation has a power failure, a side has electricity and opposite side when having a power failure in its both sides supply arm, stride institute's switch automatic closing, the supply arm power supply that makes an electric side by striding switch supply with the supply arm that opposite side does not have electricity, restore electricity rapidly.
Purpose of the present invention can realize in the following manner.
Utilize passing through of adjacent two distribution substations of former each distribution substation one to feed out cabinet, pass through two and feed out cabinet, supply arm and relevant circuit thereof with both sides, go up passing through of in the middle of each distribution substation in this basis and one feed out cabinet 3 and pass through two and feed out between the cabinet 2 and insert and stride institute's switch cubicle 4, and be provided with and stride institute's switch primary circuit accordingly, stride institute's action secondary circuit; This is striden and is provided with the contact condition of striding institute's action secondary circuit in institute's switch primary circuit, satisfy this institute power supply decompression when simultaneously, mains switch is in gate-dividing state, two of this institutes are self-closing feed out switch be in together gate-dividing state and one of this institute both sides supply arm have electricity another when not having the condition of electricity, striding the relevant relay of institute's action secondary circuit connects, then stride institute's switch automatic closing in the primary circuit, the supply arm that the adjacent institute of electric side arranged in the adjacent institute in both sides through this institute stride institute's switch and no electric side neighbour supply arm be communicated with, realization stride power;
In this electric power supplying apparatus cross substations, striding the operate time of institute's switch input is longer than adjacent being equipped with for hauling oneself willingly into the time, adjacent institute is equipped with confession and at first hauls oneself willingly into when a certain supply arm decompression, haul oneself willingly into unsuccessful, the action of institute switch side is striden by this institute, if adjacent being equipped with throws successfully, supply arm restores electricity, and it is striden the start loop disconnection of being powered and is failure to actuate;
Institute's direction is striden in the same way by distribution substation in the middle of this strides in institute's electric power system each, and each master supplier of distribution substation strides the corresponding switch control KK that connects of direction the place ahead distribution substation of institute and divides the position, back to stride institute's direction identical;
Serve as and stride the distribution substation of being powered and feed out voltage regulator and transfer to 5% by the voltage setting.
The primary circuit of electric power supplying apparatus cross substations by switching winding, closing coil respectively with stride institute's switch and connect and compose;
Stride being constructed as follows of institute's action secondary circuit: circuit I is provided with strides the normal opened contact 1YJI that a supply arm three-phase voltage relay is passed through in the reverser 1ZK of institute and this institute, 2YJI, 3YJI, the normally closed contact 4YJII of two supply arm three-phase voltage relays is passed through in this institute, 5YJII, the branch road of 6YJII series connection and stride the reverser 2ZK of institute and the normal opened contact 1YJII of two supply arm three-phase voltage relays is passed through in this institute, 2YJII, 3YJII, the normally closed contact 4YJ of a supply arm three-phase voltage relay is passed through in this institute, 5YJI, the branch road of 6YJI series connection, after the above-mentioned two branch road parallel connections with stride institute automatically, 1.-3. contact of manual change-over switch BK, this institute leads, stand-by power supply separating brake position relay normally closed contact HWJ annotates 1, HWJ annotates 2, this institute is self-closing passes through one, pass through secondary circuit separating brake position relay normally closed contact 2HWJ and annotate 3,2HWJ annotates 4, stride the time-delay position 75 of the brace 1QP of institute, time-delay relay 1SJ series connection, also with 2.-4. contact that connects switch control KK and the branch road after striding 6.-8. contact parallel connection of the automatic and hand-operated chargeover switch BK of institute connect; Circuit I I is provided with and connects switch control KK's
