Abstract
The utility model discloses a protection device of a high voltage direct current (HVDC) converter valve. The protection device of the HVDC converter valve includes an HVDC converter valve cooling device, a first intermediate relay, a second intermediate relay, a first connecting point, a second connecting point, a pressure plate and an HVDC converter valve body cooling device; the HVDC converter valve cooling device, the first intermediate relay, the first connecting point, the pressure plate and the HVDC converter valve body cooling device are connected in sequence; and the HVDC converter valve cooling device, the second intermediate relay, the second connecting point, the pressure plate and the HVDC converter valve body cooling device are connected in sequence. Since the protection device of the HVDC converter valve is provided with the second intermediate relay and the second connecting point, and the manually-controlled pressure plate is arranged between the connecting point and the HVDC converter valve body cooling device, the protection device of the HVDC converter valve has the advantages of being simple in structure, convenient in installation, and capable of preventing the protection device from the maloperation and rejection of operation.
Description
Technical field
The utility model relates to a kind of protective device of high voltage direct current converter valve.
Background technology
Existing high voltage direct current converter valve protective device is to be all connected an auxiliary relay between high voltage direct current converter valve cooling device and high voltage direct current converter valve body cooling system; when high voltage direct current converter valve cooling device sends stoppage in transit signal; drive auxiliary relay; its normal opened contact adhesive after auxiliary relay magnet exciting coil excitation, high voltage direct current converter valve body cooling system sends high voltage direct current converter valve order after receiving adhesive signal.This protective device is in auxiliary relay fault, and the signal that can cause stopping transport can not transmit, thereby causes the damage of high voltage direct current converter valve.And when needs exit high voltage direct current converter valve cooling device temporarily, need artificial dismounting loop terminals, but may make to protect malfunction in equipment dismounting in service, cause stopping transport, thereby cause huge economic loss.
Utility model content
The utility model is mainly to solve the existing technical problem of prior art, thereby provides a kind of simple in structure, easy for installation, can avoid protecting the protective device of high voltage direct current converter valve of the mistake action and rejecting action of equipment.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of protective device of high voltage direct current converter valve; comprise high voltage direct current converter valve cooling device, the first auxiliary relay, the second auxiliary relay, the first tie point, the second tie point, pressing plate and high voltage direct current converter valve body cooling system; described high voltage direct current converter valve cooling device, the first auxiliary relay, the first tie point, pressing plate and high voltage direct current converter valve body cooling system are connected successively, and described high voltage direct current converter valve cooling device, the second auxiliary relay, the second tie point, pressing plate and high voltage direct current converter valve body cooling system are connected successively.
As preferably, described the first auxiliary relay is connected with the second auxiliary relay, and described the first tie point is connected with the second tie point.
As preferably, described pressing plate moves back pressing plate for can manually throwing.
The beneficial effect of the protective device of the utility model high voltage direct current converter valve is: because the protective device of described high voltage direct current converter valve is provided with the second auxiliary relay, the second tie point; and increased manually pressing plate between tie point and high voltage direct current converter valve body cooling system; have simple in structure; easy for installation, can avoid protecting the advantage of the mistake action and rejecting action of equipment.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the theory diagram of the protective device of a kind of high voltage direct current converter valve of the utility model.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection range of the present utility model is made to more explicit defining.
Consult shown in Fig. 1, the utility model adopts following technical scheme: a kind of protective device of high voltage direct current converter valve, comprise high voltage direct current converter valve cooling device, the first auxiliary relay, the second auxiliary relay, the first tie point, the second tie point, pressing plate and high voltage direct current converter valve body cooling system, described high voltage direct current converter valve cooling device, the first auxiliary relay, the first tie point, pressing plate is connected successively with high voltage direct current converter valve body cooling system, described high voltage direct current converter valve cooling device, the second auxiliary relay, the second tie point, pressing plate is connected successively with high voltage direct current converter valve body cooling system.
Described the first auxiliary relay is connected with the second auxiliary relay, and described the first tie point is connected with the second tie point.
Described pressing plate moves back pressing plate for can manually throwing.
In the middle of equipment operation, when auxiliary relay fault or loop terminals are loosening, stoppage in transit signal can normally transmit by another auxiliary relay, prevents from protecting tripping; If desired exit high voltage direct current converter valve cooling device temporarily, can manually throw and move back pressing plate, do not need to remove connecting line terminal, prevent malfunction.
The beneficial effect of the protective device of the utility model high voltage direct current converter valve is: because the protective device of described high voltage direct current converter valve is provided with the second auxiliary relay, the second tie point; and increased manually pressing plate between tie point and high voltage direct current converter valve body cooling system; have simple in structure; easy for installation, can avoid protecting the advantage of the mistake action and rejecting action of equipment.
The above, be only embodiment of the present utility model, but protection range of the present utility model is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range that claims were limited.
